fix: restore API response formats + ai-ui-control ws + profile fields
- Restore {plugins: [...], total: N} for /plugins and /plugins/active-manifests
(flat array broke frontend PluginRegistry → no menu items → empty UI)
- Restore {count: N} for /notifications/unread-count
(scalar broke frontend notification badge)
- Fix ai_ui_control: on_install → on_activate for WS manager registration
(WS 403 on every reconnect after container restart)
- Fix double /api/v1 prefix in useAIContext.ts and SuggestionBadge.tsx
- Add first_name, last_name, avatar_url to User model + migration 0032
- Extend UserUpdate schema with profile + password change fields
- Extend user_service.update_user with profile fields + password change
- Extend frontend UserResponse/UserUpdate types
