v1.2.0: Spotify playlist improvements and admin UI fixes

Enhanced Spotify playlist integration with GraphQL API, fixed track counts and folder filtering, improved session IP tracking with X-Forwarded-For support, and added per-playlist cron scheduling.

 ### Nginx Proxy Setup (Required)
 
 This service only exposes ports internally. You can use nginx to proxy to it, however PLEASE take significant precautions before exposing this!

My recommendation is use Tailscale or something similar!

 #### How It Works
 
-1. **Spotify Import Plugin Runs** (e.g., daily at 4:15 PM)
+1. **Spotify Import Plugin Runs**
    - Plugin fetches your Spotify playlists
    - Creates/updates playlists in Jellyfin with tracks already in your library
    - Generates "missing tracks" JSON files for songs not found locally
-   - Files are named like: `Release Radar_missing_2026-02-01_16-15.json`
 
-2. **Allstarr Fetches Missing Tracks** (within sync window)
+2. **Allstarr Matches Tracks** (on startup + every 24 hours by default)
-   - Searches for missing tracks files from the Jellyfin plugin
+   - Reads missing tracks files from the Jellyfin plugin
-   - Searches **+24 hours forward first** (newest files), then **-48 hours backward** if not found
-   - This efficiently finds the most recent file regardless of timezone differences
-   - Example: Server time 12 PM EST, file timestamped 9 PM UTC (same day) → Found in forward search
-   - Caches the list of missing tracks in Redis + file cache
-   - Runs automatically on startup (if needed) and every 5 minutes during the sync window
-
-3. **Allstarr Matches Tracks** (2 minutes after startup, then configurable interval)
    - For each missing track, searches your streaming provider (SquidWTF, Deezer, or Qobuz)
    - Uses fuzzy matching to find the best match (title + artist similarity)
    - Rate-limited to avoid overwhelming the service (150ms delay between searches)
-   - Caches matched results for 1 hour
+   - Pre-builds playlist cache for instant loading
-   - **Pre-builds playlist items cache** for instant serving (no "on the fly" building)
-   - Default interval: 24 hours (configurable via `SPOTIFY_IMPORT_MATCHING_INTERVAL_HOURS`)
-   - Set to 0 to only run once on startup (manual trigger via admin UI still works)
 
-4. **You Open the Playlist in Jellyfin**
+3. **You Open the Playlist in Jellyfin**
    - Allstarr intercepts the request
    - Returns a merged list: local tracks + matched streaming tracks

-#### Startup Behavior
+#### Web UI Management
 
-When Allstarr starts with Spotify Import enabled:
+The easiest way to manage Spotify playlists is through the Web UI at `http://localhost:5275`:
 
-**Smart Cache Check:**
+1. **Link Playlists Tab**: Link Jellyfin playlists to Spotify playlists
-- Checks if today's sync window has passed (e.g., if sync is at 4 PM + 2 hour window = 6 PM)
+2. **Active Playlists Tab**: View status, trigger matching, and manage playlists
-- If before 6 PM and yesterday's cache exists → **Skips fetch** (cache is still current)
+3. **Configuration Tab**: Enable/disable Spotify Import and adjust settings
-- If after 6 PM or no cache exists → **Fetches missing tracks** from Jellyfin plugin
-
-**Track Matching:**
-- **T+2min**: Matches tracks with streaming provider (with rate limiting)
-- Only matches playlists that don't already have cached matches
-- **Result**: Playlists load instantly when you open them!
-
-**Example Timeline:**
-- Plugin runs daily at 4:15 PM, creates files at ~4:16 PM
-- You restart Allstarr at 12:00 PM (noon) the next day
-- Startup check: "Today's sync window ends at 6 PM, and I have yesterday's 4:16 PM file"
-- **Decision**: Skip fetch, use existing cache
-- At 6:01 PM: Next scheduled check will search for new files
 
 #### Troubleshooting
 
 **Playlists are empty:**
 - Check that the Spotify Import plugin is running and creating playlists
-- Verify `SPOTIFY_IMPORT_PLAYLIST_IDS` match your Jellyfin playlist IDs
+- Verify playlists are linked in the Web UI
 - Check logs: `docker-compose logs -f allstarr | grep -i spotify`
 
 **Tracks aren't matching:**
 - Ensure your streaming provider is configured (`MUSIC_SERVICE`, credentials)
-- Check that playlist names in `SPOTIFY_IMPORT_PLAYLIST_NAMES` match exactly
+- Manually trigger matching via Web UI or API
-- Manually trigger matching: `curl "https://your-proxy.com/spotify/match?api_key=KEY"`
+- Check that the Jellyfin plugin generated missing tracks files
 
-**Sync timing issues:**
+**Performance:**
-- Set `SPOTIFY_IMPORT_SYNC_START_HOUR/MINUTE` to match your plugin schedule
+- Matching runs in background with rate limiting (150ms between searches)
-- Increase `SPOTIFY_IMPORT_SYNC_WINDOW_HOURS` if files aren't being found
+- First match may take a few minutes for large playlists
-- Check Jellyfin plugin logs to confirm when it runs
+- Subsequent loads are instant (served from cache)
 
 #### Notes
 
-- This feature uses your existing `JELLYFIN_URL` and `JELLYFIN_API_KEY` settings
+- Uses your existing `JELLYFIN_URL` and `JELLYFIN_API_KEY` settings
-- Matched tracks are cached for 1 hour to avoid repeated searches
+- Matched tracks cached for fast loading
-- Missing tracks cache persists across restarts (stored in Redis + file cache)
+- Missing tracks cache persists across restarts (Redis + file cache)
-- Rate limiting prevents overwhelming your streaming provider (150ms between searches)
+- Rate limiting prevents overwhelming your streaming provider
 - Only works with Jellyfin backend (not Subsonic/Navidrome)
