Adds ntfy.sh (and self-hosted instances) as a new push notification
channel with full parity to the existing webhook channel.
- Backend: NtfyConfig type, getUserNtfyConfig, getAdminNtfyConfig,
resolveNtfyUrl, sendNtfy (header-based API with Title/Priority/Tags/
Click headers), testNtfy, NTFY_EVENT_META (priority + emoji tags per
event), SSRF guard via existing checkSsrf + createPinnedDispatcher
- notificationPreferencesService: ntfy added to NotifChannel union,
IMPLEMENTED_COMBOS, getActiveChannels parser, getAvailableChannels,
ADMIN_GLOBAL_CHANNELS, and AvailableChannels interface
- notificationService: per-user ntfy dispatch after webhook block;
admin-scoped ntfy via getAdminGlobalPref for version_available events
- Routes: POST /api/notifications/test-ntfy with saved-token fallback
- authService: admin_ntfy_server/topic/token in ADMIN_SETTINGS_KEYS,
masked + encrypted on read/write
- settingsService: ntfy_token added to ENCRYPTED_SETTING_KEYS
- Frontend: ntfy topic/server/token inputs + Save/Test/Clear buttons in
NotificationsTab; admin Ntfy panel in AdminPage; testNtfy API method
- i18n: full English strings; English placeholders in 14 other locales
- Tests: resolveNtfyUrl, sendNtfy, dispatch integration, UI tests,
MSW handler for test-ntfy endpoint
