feat: add webhook management UI and BeforeNodeDeletedEvent support

Added comprehensive webhook management capabilities including:

Webhook Client & API:
- Added WebhooksClient for Nextcloud webhooks API integration
- Create, list, update, and delete webhooks programmatically
- Support for event filters in webhook registration

Webhook Presets:
- Added preset system for common webhook configurations
- notes_sync: BeforeNodeDeletedEvent for Notes file operations
- calendar_sync: Calendar events (create, update, delete)
- deck_sync: Deck card operations
- files_sync: File system changes
- forms_sync: Form submissions (conditional)
- Filter presets by installed apps

Admin UI:
- Added multi-pane app view with tabs (User Info, Vector Sync, Webhooks)
- Webhooks tab for admin users only
- Enable/disable preset webhooks via UI
- View currently registered webhooks
- Uses htmx for dynamic loading and Alpine.js for tab state
- Admin permission checking via OCS API

CLI Improvements:
- Refactored CLI to separate module (cli.py)
- Updated entry point in pyproject.toml

BeforeNodeDeletedEvent Fix:
- Updated ADR-010 to document NodeDeletedEvent issue
- BeforeNodeDeletedEvent includes node.id before deletion
- NodeDeletedEvent lacks node.id (file already deleted)
- Implemented per Nextcloud maintainer recommendation

Testing:
- Added comprehensive webhook client tests
- Added webhook preset filtering tests
- Added admin permission tests

Configuration:
- Updated docker-compose.yml Qdrant settings

 **Impact:** The event parser in this ADR's example code assumes `event_data["node"]["id"]` exists for all file events. This will fail for deletions.
 
-**Required Fix:** Check for `id` existence and fall back to path-based identification:
+**Update (2025-11-11):** Nextcloud maintainer clarified that `BeforeNodeDeletedEvent` should be used instead of `NodeDeletedEvent` to access `node.id` before the file is deleted. See [issue #56371](https://github.com/nextcloud/server/issues/56371#issuecomment-2470896634).
+
+> "Try using the `BeforeNodeDeletedEvent`. The `id` should still be available at that time. The reason `id` is not in `NodeDeletedEvent` is because the file is effectively guaranteed to be gone and, in turn, so is the FileInfo."
+> — Josh Richards, Nextcloud maintainer
+
+**Recommended Solution:** Use `OCP\Files\Events\Node\BeforeNodeDeletedEvent` for file deletion webhooks instead of `NodeDeletedEvent`.

+**Alternative Fix (if using NodeDeletedEvent):** Check for `id` existence and fall back to path-based identification:
