Replace the ad-hoc "workspace" abstraction with a focused, URL-driven
"sidebar view" registry that implements the modern Vercel / Cloudflare
drill-in pattern: clicking a top-level entry (e.g. System Settings)
swaps the sidebar to a contextual workspace, with a `← Back to
Dashboard` affordance, instead of stacking sub-navigation in the root.

Architecture
------------
- types.ts
    + SidebarView           — declarative nested view config
                              (id, pathPattern, parent, getNavGroups)
    + SidebarViewParent     — back-navigation descriptor
    + ResolvedSidebarView   — { key, view, navGroups } returned by hook
    + SidebarData           — slimmed to { navGroups } only
    - Workspace             — removed (logo/plan never rendered)

- lib/sidebar-view-registry.ts (new, replaces workspace-registry.ts)
    + SIDEBAR_VIEWS array — single source of truth for nested views
    + resolveSidebarView(pathname)
    + getNavGroupsForPath(pathname, t) — back-compat helper for the
      command palette

- config/system-settings.config.ts
    Refactored to export a single SYSTEM_SETTINGS_VIEW (SidebarView)
    with parent `/dashboard/overview` + label `Back to Dashboard`.

- components/sidebar-view-header.tsx (new)
    Renders only the back affordance (chevron + label). Uses the
    default SidebarMenuButton size so its typography matches the
    nav items below; collapses gracefully into icon mode via the
    existing tooltip behavior. The redundant "title + icon" row was
    removed — workspace context is already carried by the nav groups.

- hooks/use-sidebar-view.ts (new)
    Encapsulates view resolution and root-nav filtering:
      · matched view  → returns its nav groups verbatim (route-level
                        beforeLoad guards already enforce access);
      · no match      → returns root nav groups, narrowed by user
                        role (admin gate) and useSidebarConfig
                        (admin × user sidebar_modules overlay).

- components/app-sidebar.tsx
    Now a thin presentation layer: reads { key, view, navGroups }
    from useSidebarView() and orchestrates the view transition via
    AnimatePresence + MOTION_VARIANTS.sidebarSlide (respects
    prefers-reduced-motion). No logic, no role checks, no path
    matching — those live in the hook.

- components/command-menu.tsx
    Switched to the new getNavGroupsForPath() API; behavior preserved.

Cleanup
-------
- Deleted layout/context/workspace-context.tsx (zero consumers).
- Deleted layout/lib/workspace-registry.ts and its
  workspace-registry.example.ts companion (over-abstracted: name/id
  metadata, isInWorkspace / getAllWorkspaces / WORKSPACE_IDS were
  registered but never read).
- Removed `workspaces` field from useSidebarData (never consumed
  after the top-switcher was dropped).
- Dropped WorkspaceProvider from authenticated-layout.tsx.
- Trimmed dead `Manage and configure` translation key from all six
  locale files and from static-keys.ts.

i18n
----
Added the `Back to Dashboard` key to en, zh, fr, ja, ru, vi, and
registered it in static-keys.ts under "Sidebar views".

Verification
------------
- bun run typecheck: passes
- Lint: no new warnings/errors on the touched files
- Adding a new drill-in workspace now only requires registering a
  SidebarView in SIDEBAR_VIEWS — no changes to AppSidebar required.

* 🐛 fix(channel): evict auto-disabled multi-key channels from cache

Ensure multi-key channels are removed from the in-memory routing cache when all keys become auto-disabled, preventing subsequent requests from repeatedly selecting channels with no available keys.

Also make multi-key status updates more robust by handling missing key matches, checking actual enabled key availability, and restoring the channel status when a key is re-enabled. Add regression coverage for disabled cached channels and multi-key cache eviction.

Three layered optimizations targeting Gemini-style 5MB base64 payloads where
RSS could balloon to tens of GB under concurrent load:

1. Byte-based param override (relay/common/override.go)
   - Switch legacy/operations hot paths from common.Marshal round-trips and
     map[string]any conversions to gjson/sjson on []byte directly.
   - Avoids cloning 5MB strings during each Set/Delete operation.

2. strings.Builder for Gemini response markdown (relay/channel/gemini/relay-gemini.go)
   - Replace string concatenation + strings.Join when assembling
     "![image](data:...;base64,DATA)" content for inline image responses.
   - Pre-allocates capacity from inline_data byte sizes.

3. Outbound BodyStorage + streaming Decoder (this commit's core)
   - New relay/common/outbound_body.go helper wraps marshaled upstream bodies
     in common.BodyStorage, allowing disk-cache mode to offload jsonData to
     a temp file while waiting for upstream TTFB. The original []byte can
     then be GC'd, removing ~5MB/req of heap residency during the longest
     window of a request.
   - All 7 relay handlers (gemini/claude/responses/embedding/image/compatible/
     rerank) plus chat_completions_via_responses adopt the helper with
     defer closer.Close() and explicit jsonData = nil.
   - relay/common/relay_info.go: new UpstreamRequestBodySize so
     relay/channel/api_request.go can populate req.ContentLength (lost when
     body becomes a type-erased io.Reader).
   - common/gin.go UnmarshalBodyReusable: when storage is disk-backed and
     content-type is JSON, decode via DecodeJson(storage) instead of
     storage.Bytes()+Unmarshal, removing one transient 5MB copy per request.
     memory mode and form/multipart paths unchanged.

This reverts commit 554defe4.

Users reported that the API key edit drawer's "Save changes" button
becomes unresponsive after the drawer has been open / idle for a
while: no loading state, no request, no error. Reopening the drawer
restores it because a fresh DOM is created.

The button lived in `SheetFooter` (a portaled Base UI Sheet) and was
linked to the form via the HTML `form='api-key-form'` attribute. Once
the portal/DOM relationship goes stale, the click no longer triggers
the form's submit event, hence the silent failure.

Defensive fix: drop the cross-DOM `form` linkage and call
`form.handleSubmit(onSubmit)` directly via `onClick`. The native
submit path (Enter key, original `<form onSubmit>`) is preserved.

Closes #4858

The faceted filter popover used a fixed width of 200px, which clipped
long option labels (e.g. user-defined channel group names) and forced
the truncated text to be unreadable without leaving a way to see the
full value.

- Switch PopoverContent from `w-[200px]` to
  `min-w-[200px] max-w-[360px]` so short option lists keep their
  current footprint while long labels can expand up to 360px before
  the existing truncate kicks in.
- Add `title={t(option.label)}` on the truncated label span so users
  can still hover to see the full text on extreme cases.

Closes #4905

The new UI's sign-up form sent the invite code under key `aff`, but
the backend `Register` controller binds it to `User.AffCode` whose
JSON tag is `aff_code` (see model/user.go). Result: every invited
sign-up landed with `inviter_id = 0`, breaking the affiliate flow.

Rename only the request payload field so it matches the backend
contract. URL query parameter (`/sign-up?aff=...`), localStorage key
and OAuth state continue to use `aff` and are unchanged.

Closes #4945

Selected preset buttons looked identical to unselected in dark mode: the
override classes `border-foreground bg-foreground/5` carry no `dark:`
variant, while the Button `outline` variant base contains
`dark:border-input dark:bg-input/30`. tailwind-merge keeps both (different
variants → no conflict), and in dark mode CSS specificity makes
`.dark .border-input` win over `.border-foreground`, so the override is
silently overridden and the bright-border/tinted-bg selection state never
applies.

Add explicit `dark:border-foreground dark:bg-foreground/10` to the
override so tailwind-merge resolves the dark-variant conflict in favor
of the override and the selected state is clearly distinguishable on
both light and dark backgrounds.

* fix(auth): localize reset password confirmation

Wrap reset confirmation page copy in frontend i18n calls and add matching locale entries so the page no longer mixes translated labels with hardcoded English copy.

* fix(auth): use semantic reset i18n keys

Change 'Previous' to 'Previous page' and 'Next' to 'Next page'
for improved clarity in the ModelCardGrid component.

/api/status never returned `register_enabled` or `password_register_enabled`,
so the sign-in page had no way to react when an admin disabled registration.
The "Sign up" link was only gated on `self_use_mode_enabled`, which is a
separate and unrelated concept (single-user vs. multi-user deployment).

Result: toggling "Registration Enabled" in admin settings had no visible
effect on the login page — users could still see the sign-up link even when
registration was disabled, and could not see it even when it was enabled
(if the system happened to be in self-use mode from initial setup).

Fix:
- Add `register_enabled` and `password_register_enabled` to GetStatus()
- Gate the "Sign up" link on `register_enabled !== false` in addition to
  the existing `!self_use_mode_enabled` check

The "Send reset email" button was missing type="submit", preventing
form submission when clicked. All other auth forms (sign-in, sign-up,
OTP) already have this attribute set correctly.

fix: qualify column names in PerfMetric upsert to avoid PG ambiguity

When users filter channels by group without entering a search keyword,
the frontend calls GetAllChannels (GET /api/channel/) instead of
SearchChannels. However, GetAllChannels did not process the group
query parameter, causing the filter to have no effect.

Added group filtering logic to GetAllChannels for both normal mode
and tag mode, using the same CONCAT/|| pattern as SearchChannels
for cross-database compatibility (MySQL, PostgreSQL, SQLite).
