Skip refresh attempt if client_id/secret not configured — clears stale
tokens to stop retry loop permanently. Add 5-minute backoff after
failed refresh to prevent hammering Tidal API every 2 seconds.
Updates the method for obtaining the next cursor during track pagination to use the approach from PR #113, retrieving it from 'links.meta.nextCursor' instead of 'meta.nextCursor'. This ensures correct pagination behavior.
Rewrites playlist and track fetching to use Tidal's JSON:API endpoints with cursor-based pagination and batch track hydration. Adds robust rate limiting with retry logic, and introduces ISO-8601 duration parsing. This improves reliability, performance, and compatibility with Tidal's latest API structure.
Redirect URIs for Spotify and Tidal OAuth are now configurable via the web UI and settings. Updated backend clients to use the configured redirect URI if provided, improving flexibility for deployments with custom callback URLs.
Introduces web server routes and UI buttons for initiating Spotify and Tidal OAuth authentication flows, with dedicated callback servers for token exchange. Updates Docker ports for OAuth callbacks and refines PKCE handling for Tidal. Improves user experience by allowing authentication directly from the web UI.
