Backend:
• ConsoleSetting
  - Introduce `ApiInfoEnabled`, `UptimeKumaEnabled`, `AnnouncementsEnabled`, `FAQEnabled` (default true).
• misc.GetStatus
  - Refactor to build response map dynamically.
  - Return the four *_enabled flags.
  - Only append `api_info`, `announcements`, `faq` when their respective flags are true.

Frontend:
• Detail page
  - Remove all `self_use_mode_enabled` checks.
  - Render API, Announcement, FAQ and Uptime panels based on the new *_enabled flags.
• Dashboard → Settings
  - Added `Switch` controls in:
    · SettingsAPIInfo.js
    · SettingsAnnouncements.js
    · SettingsFAQ.js
    · SettingsUptimeKuma.js
  - Each switch persists its state via `/api/option` to the corresponding
    `console_setting.<panel>_enabled` key and reflects current status on load.
  - DashboardSetting.js now initialises and refreshes the four *_enabled keys so
    child components receive accurate panel states.

Fixes:
• Switches previously defaulted to “on” because *_enabled keys were missing.
  They are now included, ensuring correct visual state when panels are disabled.

No breaking changes; existing functionality remains untouched aside from the
new per-panel visibility control.
