Chris Coutinho 5b71ac3251 fix(astrolabe): add locking to prevent token refresh race condition
Adds distributed locking using Nextcloud's ILockingProvider to prevent
race conditions between background job and on-demand token refresh.

Uses double-check locking pattern:
1. Quick check without lock - return immediately if token is valid
2. Acquire exclusive lock if token needs refresh
3. Re-check after lock - another process may have refreshed
4. Refresh only if still needed
5. Graceful degradation on LockedException

Changes:
- McpTokenStorage: add ILockingProvider, withTokenLock() method
- McpTokenStorage: update getAccessToken() with locking pattern
- RefreshUserTokens: wrap refresh in withTokenLock(), catch LockedException
- Add comprehensive unit tests for locking behavior

Chris Coutinho c46f9eb212 fix(astrolabe): add issued_at to on-demand token refresh
Fixes missing issued_at parameter when storing tokens refreshed via
getAccessToken() callback, ensuring accurate token lifetime calculation
for the background refresh job.

Chris Coutinho 28219e00e7 feat(astrolabe): add background token refresh job
Prevents users from having to re-authorize Astrolabe after periods of
inactivity by proactively refreshing OAuth tokens before they expire.

Changes:
- Add RefreshUserTokens background job that runs every 15 minutes
- Add on-demand token refresh in SemanticSearchProvider (Unified Search)
- Store issued_at timestamp for accurate token lifetime calculation
- Add getAllUsersWithTokens() to query users needing refresh

The job dynamically calculates refresh threshold based on actual token
lifetime (50% remaining), working with any IdP (Nextcloud OIDC, Keycloak,
etc.) rather than relying on IdP-specific configuration.

Closes #510

Chris Coutinho d5544a7731 refactor(astrolabe): replace client-side PDF.js with server-side PyMuPDF rendering
Replace the client-side PDF.js viewer with server-side rendering using PyMuPDF.
This avoids CSP worker restrictions and ES private field access issues that
affected Chromium browsers.

Changes:
- Add /api/v1/pdf-preview endpoint to MCP server (management.py)
- Add pdf-preview route and controller action in Astrolabe PHP backend
- Refactor PDFViewer.vue to display server-rendered PNG images
- Remove pdfjs-dist dependency and client-side PDF loading code
- Use @nextcloud/axios for CSRF token handling in PDFViewer

The server downloads the PDF via WebDAV, renders the requested page with
PyMuPDF at the specified scale, and returns a base64-encoded PNG image.

Chris Coutinho f0ade4ad28 refactor(astrolabe): add PHP property types to fix Psalm errors
Add explicit property type declarations to IdpTokenRefresher,
CredentialsController, OAuthController, and McpServerClient classes.
This improves type safety and allows Psalm to properly infer types,
eliminating MissingPropertyType and many MixedMethodCall errors.

Also adds IClient import where needed and validates getSystemValue
returns to ensure string types before use.

Chris Coutinho 737f10f190 fix(astrolabe): improve token refresh error handling and validation
- Extract magic number to TOKEN_EXPIRY_BUFFER_SECONDS constant
- Add URL validation for astrolabe_internal_url with fallback
- Warn when internal URL uses external port mapping (misconfiguration)
- Differentiate HTTP error handling by status code:
  - Network errors (LocalServerException): warning level
  - Auth errors (401/403): error level (token invalid)
  - Server errors (500+): warning level (transient)
- Reduce log level for IdP selection messages to debug
- Add integration tests for credential storage, isolation, and revoke/reprovision

Chris Coutinho e48c5fa9a2 fix(astrolabe): delete stale tokens when refresh fails
- Delete stored token when refresh callback fails or returns null
- Delete stored token when expired with no refresh callback available
- Fix test namespaces (Service → OCA\Astrolabe\Tests\Unit\Service)
- Update tests to verify token deletion on refresh failure

Prevents repeated refresh attempts with stale tokens that will never
succeed, improving error handling and reducing unnecessary API calls.

Chris Coutinho 79cfb65590 fix(astrolabe): use internal URL for OAuth token refresh
The IdpTokenRefresher was incorrectly using overwrite.cli.url (the
external URL like http://localhost:8080) for internal token refresh
requests. This URL is not accessible from inside Docker containers
since port 8080 is only mapped on the host machine.

Changed getNextcloudBaseUrl() to:
- Always use http://localhost (internal port 80) by default
- Added optional astrolabe_internal_url config for custom setups
- Removed overwrite.cli.url usage (intended for external URLs only)

This fixes 401 errors in Astrolabe semantic search when OAuth tokens
need to be refreshed in containerized deployments.

Chris Coutinho 1cc460b0d8 fix(astrolabe): Address reviewer feedback for hybrid mode
Addresses code review feedback:

Personal.php:
- Consolidate template variables to use camelCase consistently
- Remove duplicate snake_case variables (auth_mode, supports_app_passwords)
- Add oauthUrl to standard OAuth mode parameters (fixes fallback issue)
- Add requesttoken for CSRF protection

personal.php (template):
- Use null coalescing for safe variable access
- Reuse computed $isHybridMode variable instead of duplicate check
- Remove complex fallback URL logic (oauthUrl now always provided)

IdpTokenRefresher.php:
- Use Nextcloud's overwrite.cli.url config when available
- Fall back to http://localhost for container deployments
- Better supports non-containerized environments

Chris Coutinho c95459234b fix(astrolabe): fix OAuth flow and settings UI for hybrid mode
In hybrid mode (multi_user_basic + offline_access), users need BOTH:
- OAuth token for Astrolabe→MCP API calls
- App password for MCP→Nextcloud background sync

Changes:
- Personal.php: Pass correct oauthUrl pointing to Astrolabe's OAuth
  controller instead of MCP server's browser OAuth. Check both OAuth
  token AND app password status in hybrid mode.
- personal.php template: Show two-step workflow UI requiring both
  credentials before showing "Active" status. Each step shows
  completion badges.
- IdpTokenRefresher.php: Use http://localhost for internal token
  refresh requests (consistent with OAuthController). External URLs
  like localhost:8080 don't work from inside the container.

Fixes 401 errors when searching in Astrolabe with hybrid deployment.

Chris Coutinho 65c3f099fa 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
