Implements native Matrix notification channel support, allowing users
to receive service alerts in any Matrix room via the Client-Server API.
Changes:
- server/service-operation/notification/matrix.go: new Matrix service
implementing the NotificationService interface (PUT /_matrix/client/v3/...)
- server/service-operation/notification/types.go: add MatrixHomeserver,
MatrixRoomID, MatrixAccessToken fields to AlertConfiguration
- server/service-operation/notification/manager.go: register MatrixService
- server/pb_migrations/1772200000_updated_alert_configurations_matrix.js:
PocketBase migration adding matrix fields and notification_type value
- application: Matrix option in channel dialog with homeserver/room/token
fields, tab filter, list display, type definitions and translations (en, km)
- application/public/upload/notification/matrix.png: Matrix channel icon
- Add Gotify as a new channel type in the notification settings. The Gotify channel will use the `api_token` and `server_url` field for API key storage in PB.
- Adds Pushover as a new notification channel option. Includes fields for `api_token` and `user_key` in the `alert_configurations` schema and integrates it into the channel type dropdown and form handling.
- Adds NTFY as a new option to the notification channel type dropdown
- This includes updating the form schema and related components to support the ntfy_endpoint field for NTFY configurations.
