- Update PricingCardSkeleton grid classes from 'sm:grid-cols-2 lg:grid-cols-3'
  to 'xl:grid-cols-2 2xl:grid-cols-3' to match PricingCardView layout
- Ensures consistent column count between skeleton and actual content
  at same screen sizes
- Improves loading state visual consistency across different breakpoints

- **Backend Changes:**
  - Refactor pricing API to return separate vendors array with ID-based model references
  - Remove redundant vendor_name/vendor_icon fields from pricing records, use vendor_id only
  - Add vendor_description to pricing response for frontend display
  - Maintain 1-minute cache protection for pricing endpoint security

- **Frontend Data Flow:**
  - Update useModelPricingData hook to build vendorsMap from API response
  - Enhance model records with vendor info during data processing
  - Pass vendorsMap through component hierarchy for consistent vendor data access

- **UI Component Replacements:**
  - Replace PricingCategories with PricingVendors component for vendor-based filtering
  - Replace PricingCategoryIntro with PricingVendorIntro in header section
  - Remove all model category related components and logic

- **Header Improvements:**
  - Implement vendor intro with real backend data (name, icon, description)
  - Add text collapsible feature (2-line limit with expand/collapse functionality)
  - Support carousel animation for "All Vendors" view with vendor icon rotation

- **Model Detail Modal Enhancements:**
  - Update ModelHeader to use real vendor icons via getLobeHubIcon()
  - Move tags from header to ModelBasicInfo content area to avoid SideSheet title width constraints
  - Display only custom tags from backend with stringToColor() for consistent styling
  - Use Space component with wrap property for proper tag layout

- **Table View Optimizations:**
  - Integrate RenderUtils for description and tags columns
  - Implement renderLimitedItems for tags (max 3 visible, +x popover for overflow)
  - Use renderDescription for text truncation with tooltip support

- **Filter Logic Updates:**
  - Vendor filter shows disabled options instead of hiding when no models match
  - Include "Unknown Vendor" category for models without vendor information
  - Remove all hardcoded vendor descriptions, use real backend data

- **Code Quality:**
  - Fix import paths after component relocation
  - Remove unused model category utilities and hardcoded mappings
  - Ensure consistent vendor data usage across all pricing views
  - Maintain backward compatibility with existing pricing calculation logic

This refactor provides a more scalable vendor-based architecture while eliminating
data redundancy and improving user experience with real-time backend data integration.

feat: improve layout and pagination handling in MultiKeyManageModal

feat: implement two-factor authentication (2FA) support with user login and settings integration

feat: add multi-key management

Add flexible model name matching system to support different matching patterns:

Backend changes:
- Add `name_rule` field to Model struct with 4 matching types:
  * 0: Exact match (default)
  * 1: Prefix match
  * 2: Contains match
  * 3: Suffix match
- Implement `FindModelByNameWithRule` function with priority order:
  exact > prefix > suffix > contains
- Add database migration for new `name_rule` column

Frontend changes:
- Add "Match Type" column in models table with colored tags
- Add name rule selector in create/edit modal with validation
- Auto-set exact match and disable selection for preconfigured models
- Add explanatory text showing priority order
- Support i18n for all new UI elements

This enables users to define model patterns once and reuse configurations
across similar models, reducing repetitive setup while maintaining exact
match priority for specific overrides.

Closes: #[issue-number]

Summary
• Backend
  1. model/model_meta.go
     – Added `QuotaType` field to `Model` struct (JSON only, gorm `-`).
  2. model/model_groups.go
     – Implemented `GetModelQuotaType(modelName)` leveraging cached pricing map.
  3. controller/model_meta.go
     – Enhanced `fillModelExtra` to populate `QuotaType` using new helper.

• Frontend
  1. web/src/components/table/models/ModelsColumnDefs.js
     – Introduced `renderQuotaType` helper that visualises billing mode with coloured tags (`teal = per-call`, `violet = per-token`).
     – Added “计费类型” column (`quota_type`) to models table.

Why
Providing the billing mode alongside existing pricing/group information gives administrators instant visibility into whether each model is priced per call or per token, aligning UI with new backend metadata.

Notes
No database migration required – `quota_type` is transient, delivered via API. Frontend labels/colours can be adjusted via i18n or theme tokens if necessary.

- Add new PrefillGroup model with CRUD operations
  * Support for model, tag, and endpoint group types
  * JSON storage for group items with GORM datatypes
  * Automatic database migration support

- Implement backend API endpoints
  * GET /api/prefill_group - List groups by type with admin auth
  * POST /api/prefill_group - Create new groups
  * PUT /api/prefill_group - Update existing groups
  * DELETE /api/prefill_group/:id - Delete groups

- Add comprehensive frontend management interface
  * PrefillGroupManagement component for group listing
  * EditPrefillGroupModal for group creation/editing
  * Integration with EditModelModal for auto-filling
  * Responsive design with CardTable and SideSheet

- Enhance model editing workflow
  * Tag group selection with auto-fill functionality
  * Endpoint group selection with auto-fill functionality
  * Seamless integration with existing model forms

- Create reusable UI components
  * Extract common rendering utilities to models/ui/
  * Shared renderLimitedItems and renderDescription functions
  * Consistent styling across all model-related components

- Improve user experience
  * Empty state illustrations matching existing patterns
  * Fixed column positioning for operation buttons
  * Item content display with +x indicators for overflow
  * Tooltip support for long descriptions

Backend
• model/model_meta.go
  – Added `EnableGroups []string` to Model struct
  – fillModelExtra now populates EnableGroups

• model/model_groups.go
  – New helper `GetModelEnableGroups` (reuses Pricing cache)

• model/pricing_refresh.go
  – Added `RefreshPricing()` to force immediate cache rebuild

• controller/model_meta.go
  – `GetAllModelsMeta` & `SearchModelsMeta` call `model.RefreshPricing()` before querying, ensuring groups / endpoints are up-to-date

Frontend
• ModelsColumnDefs.js
  – Added `renderGroups` util and “可用分组” table column displaying color-coded tags

Result
Admins can now see which user groups can access each model, and any ability/group changes are reflected instantly without the previous 1-minute delay.

Overview
• Re-designed `MissingModelsModal` to align with `ModelTestModal` and deliver a cleaner, paginated experience.
• Improved mobile responsiveness for action buttons in `ModelsActions`.

Details
1. MissingModelsModal.jsx
   • Switched from `List` to `Table` for a more structured view.
   • Added search bar with live keyword filtering and clear icon.
   • Implemented pagination via `MODEL_TABLE_PAGE_SIZE`; auto-resets on search.
   • Dynamic rendering: when no data, show unified Empty state without column header.
   • Enhanced header layout with total-count subtitle and modal corner rounding.
   • Removed unused `Typography.Text` import.

2. ModelsActions.jsx
   • Set “Delete Selected Models” and “Missing Models” buttons to `flex-1 md:flex-initial`, placing them on the same row as “Add Model” on small screens.

Result
The “Missing Models” workflow now offers quicker discovery, a familiar table interface, and full mobile friendliness—without altering API behavior.

Highlights
• Introduced `Typography.Text` link with `IconLink` in `extraText` for the **icon** field, pointing to LobeHub’s full icon catalogue; only “请点击我” is clickable for clarity.
• Added required imports for `Typography` and `IconLink`.
• Removed unnecessary `size="large"` prop from the status `Form.Switch` to align with default form styling.

These tweaks improve user guidance when selecting vendor icons and refine the modal’s visual consistency.

Introduce a generic `renderLimitedItems` helper within `ModelsColumnDefs.js` to eliminate duplicated logic for list-style columns.

Key changes
• Added `renderLimitedItems` to handle item limiting, “+N” indicator, and popover display.
• Migrated `renderTags`, `renderEndpoints`, and `renderBoundChannels` to use the new helper.
• Removed redundant inline implementations, reducing complexity and improving readability.
• Preserved previous UX: first 3 items shown, overflow accessible via popover.

This refactor streamlines code maintenance and ensures consistent behavior across related columns.
