feat: add ENABLE_USER_STATUS toggle for admin-controlled user status visibility

Add a new admin panel toggle (Admin > Settings > General) called "User Status" that allows administrators to globally enable or disable user status functionality.

When disabled:
- User status API endpoints return 403 Forbidden
- Status emoji, message, and "Update your status" button are hidden from the user menu

The setting:
- Defaults to True (enabled)
- Can be overridden via ENABLE_USER_STATUS environment variable
- Persists across restarts using PersistentConfig

Files modified:
- backend/open_webui/config.py - Added ENABLE_USER_STATUS PersistentConfig
- backend/open_webui/main.py - App state init and features dict
- backend/open_webui/routers/auths.py - AdminConfig model and endpoints
- backend/open_webui/routers/users.py - 403 guards on status endpoints
- src/lib/components/admin/Settings/General.svelte - Toggle UI
- src/lib/components/layout/Sidebar/UserMenu.svelte - Conditional status display

* Update UserMenu.svelte
