 *

 *     summary: SSE stream for real-time updates
 *     description: |
 *       Server-Sent Events (SSE) stream that pushes download data to the client on every poll cycle.
 *       Uses the browser's built-in EventSource API (no library required).
 *
 *       **Authentication:** Requires valid `emby_user` cookie. CSRF token NOT required (GET request).
 *
 *       **SSE Event Format:**
 *       - Initial payload sent immediately on connection
 *       - Subsequent payloads sent after each poll cycle (or webhook-triggered refresh)
 *       - Each payload is a `data:` frame containing JSON with `user`, `isAdmin`, `downloads`, and `downloadClients`
 *       - Heartbeat comment (`: heartbeat`) sent every 25 seconds to keep connection alive
 *       - Optional `history-update` event when history is refreshed
 *
 *       **Payload Structure:**
 *       ```json
 *       {
 *         "user": "john",
 *         "isAdmin": false,
 *         "downloads": [...],
 *         "downloadClients": [

 *         ]
 *       }
 *       ```
 *
 *       **Filtering:**
 *       - Non-admin users: Only see downloads tagged with their username
 *       - Admin users: Can see all downloads by setting query parameter `showAll=true`
 *
 *       **Connection Management:**
 *       - Server tracks active clients for cleanup and admin status panel
 *       - On client disconnect: deregisters callback, stops heartbeat, removes from active clients
 *       - Browser's EventSource API handles automatic reconnection on network interruption
 *
 *       **Headers:**
 *       - Content-Type: text/event-stream
 *       - Cache-Control: no-cache, no-transform
 *       - Connection: keep-alive
 *       - X-Accel-Buffering: no (disables nginx proxy buffering)
 *
 *       **x-integration-notes:** Use EventSource in browser:
 *       ```javascript
 *       const eventSource = new EventSource('/api/dashboard/stream', { withCredentials: true });
 *       eventSource.onmessage = (event) => {

 *   post:
 *     tags: [Dashboard]
 *     summary: Blocklist and re-search
 *     description: |
 *       Admin-only endpoint that removes a queue item from Sonarr/Radarr with blocklist=true
 *       (so the release is not grabbed again), then immediately triggers a new automatic search
 *       for the same episode/movie.
 *
 *       **Authentication:** Requires valid `emby_user` cookie (admin only) and `X-CSRF-Token` header.
 *
 *       **Workflow:**
 *       1. Validate user is admin
 *       2. Validate all required fields are present
 *       3. Delete queue item from Sonarr/Radarr with `removeFromClient=true` and `blocklist=true`
 *       4. Trigger automatic search command:
 *          - Sonarr: EpisodeSearch with episodeIds
 *          - Radarr: MoviesSearch with movieIds
 *       5. Invalidate poll cache so next SSE push reflects the removed item
 *
 *       **Required Fields:**
 *       - `arrQueueId`: Sonarr/Radarr queue record ID
 *       - `arrType`: Must be "sonarr" or "radarr"
 *       - `arrInstanceUrl`: Base URL of the *arr instance
 *       - `arrInstanceKey`: API key for the *arr instance
 *       - `arrContentId`: episodeId (Sonarr) or movieId (Radarr)
 *       - `arrContentType`: Must be "episode" (Sonarr) or "movie" (Radarr)
 *
 *       **Error Responses:**
 *       - 403: Non-admin user attempts access
 *       - 400: Missing required fields or invalid arrType
 *       - 502: Failed to communicate with *arr instance
 *
 *       **x-integration-notes:** This endpoint is used from the dashboard UI when an admin
 *       clicks "Blocklist + Re-search" on a failed download. The arr instance credentials
 *       are passed from the download object (which includes them for admin users).
