docs(swagger): add JSDoc @openapi for webhook endpoints

- POST /api/webhook/sonarr: secret validation, rate-limited, replay protection
- POST /api/webhook/radarr: identical processing logic
- Document X-Sofarr-Webhook-Secret header requirement
- List all valid eventType values
- Document event classification (QUEUE vs HISTORY)
- Include replay protection window (5 minutes)

/**
* POST /api/webhook/sonarr
* Receives webhook events from Sonarr instances.
* Validates the secret, logs the event, refreshes cache, broadcasts SSE, and returns 200.
* @openapi
* /api/webhook/sonarr:
* post:
* tags: [Webhook]
* summary: Sonarr webhook receiver
* description: |
* Receives webhook events from Sonarr instances. Validates the secret, logs the event,
* refreshes cache, broadcasts SSE, and returns 200 immediately (fire-and-forget processing).
*
* Phase 2: integrated with PALDRA cache + SSE for real-time dashboard updates.
* Phase 6: rate limiting, input validation, replay protection.
* **Authentication:** Requires `X-Sofarr-Webhook-Secret` header matching `SOFARR_WEBHOOK_SECRET`.
* No cookie authentication required (webhooks come from Sonarr, not browsers).
*
* **Rate Limiting:** 60 requests per minute per IP.
*
* **Validation:**
* - Secret validation via `X-Sofarr-Webhook-Secret` header
* - Payload validation (must be JSON object with eventType, instanceName, date)
* - Event type must be in allowlist (Test, Grab, Download, DownloadFailed, etc.)
* - Replay protection: rejects duplicate events within 5-minute window
*
* **Event Classification:**
* - QUEUE_EVENTS (Grab, Download, DownloadFailed, ManualInteractionRequired):
* Refreshes `poll:sonarr-queue` cache
* - HISTORY_EVENTS (DownloadFolderImported, ImportFailed, EpisodeFileRenamed, etc.):
* Refreshes `poll:sonarr-history` cache
* - Informational events (Test, Rename, Health, etc.):
* Logged but no cache refresh
*
* **Processing Flow:**
* 1. Validate secret → 401 if invalid
* 2. Validate payload → 400 if invalid
* 3. Check replay cache → 200 with duplicate=true if replay
* 4. Update webhook metrics (enables smart polling skip)
* 5. Return 200 immediately (don't wait for background processing)
* 6. Background: fetch fresh data from Sonarr, update cache, broadcast SSE
*
* **x-integration-notes:** Configure Sonarr webhook:
* - URL: `{SOFARR_BASE_URL}/api/webhook/sonarr`
* - Method: POST
* - Header: `X-Sofarr-Webhook-Secret: {SOFARR_WEBHOOK_SECRET}`
