feat(notifications): ntfy/Gotify push channels with live delivery (#69 )

Per-user notification_channels (ntfy + Gotify): every insertUserNotification now fans out best-effort to enabled channels — deployment/backup/security/agent alerts reach the user's phone via the ntfy app with zero extra infrastructure. - POST/GET/DELETE /notifications/channels + POST .../:id/test which pushes a real probe so misconfiguration surfaces before alerts depend on it (502 DELIVERY_FAILED on endpoint errors). - ntfy: POST to endpoint (topic in path), Title/Tags headers, optional Bearer token. Gotify: POST {endpoint}/message?token=... - Delivery is best-effort by design — a dead relay never breaks the producing flow; one shared 5s-timeout client. - CLI `notifications channels list|add|test|remove`, MCP tools, OpenAPI paths + NotificationChannel schema. - Web settings "Push notifications" section and a Push channels card on the mobile notifications tab (add/test/remove). Verified live: channel CRUD, test-ping hit a recording endpoint with correct headers/body, and a real deployment fanned out "Deployment succeeded" through the channel end-to-end.
