feat(astrolabe): implement app password provisioning for multi-user background sync

Adds complete app password provisioning workflow for multi-user BasicAuth deployments, allowing users to independently enable background sync by generating and storing Nextcloud app passwords. **New Components:** Backend (PHP): - CredentialsController: Validates and stores app passwords * Validates app password format and authenticity via OCS API * Stores encrypted passwords in oc_preferences * Provides status and credential management endpoints - AstrolabeAdminSettings: Admin configuration page for MCP server URL - AstrolabeAdminSettingsListener: Event listener for admin section - Updated McpTokenStorage: Added background sync credential methods Frontend: - personalSettings.js: Form handling for app password entry * AJAX submission with error handling * Shows success/error notifications * Triggers page reload after successful save - settings.css: Styling for settings pages - Updated personal.php template: Two-option UI * Option 1: OAuth refresh token (future, not yet available) * Option 2: App password (works today, recommended) * Shows "Active" badge when provisioned * Displays credential type and provisioned timestamp Routes: - POST /api/v1/background-sync/credentials - Store app password - GET /api/v1/background-sync/status - Get provisioning status - DELETE /api/v1/background-sync/credentials - Revoke credentials - GET /api/v1/background-sync/credentials/{userId} - Admin only **Testing:** - test_astrolabe_settings_buttons.py: Integration test for UI buttons **Workflow:** 1. User generates app password in Nextcloud Security settings 2. User navigates to Astrolabe personal settings 3. User enters app password in "Option 2: App Password" form 4. Backend validates password via OCS API call 5. Password stored encrypted in oc_preferences 6. Page reloads showing "Active" badge with credential details 7. MCP server can now use stored password for background operations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
