Hotfix Release - Critical Plex API Update

This is a critical hotfix that addresses breaking changes in Plex's API infrastructure. Pulsarr will not function without this update.

Fixed Plex API Endpoint Changes

Issue: Plex changed their discovery API endpoint from metadata.provider.plex.tv to discover.provider.plex.tv
Root Cause: Plex infrastructure migration broke all watchlist fetching functionality
Fix: Updated all Plex API calls to use the new discover.provider.plex.tv endpoint
Impact: Restores all watchlist functionality - without this fix, Pulsarr cannot fetch any watchlists
File: src/utils/plex.ts

Enhanced Plex API Security

Issue: X-Plex-Token was being passed in URL parameters, potentially exposing tokens in logs and proxies
Root Cause: Security vulnerability where authentication tokens could be leaked
Fix: Moved X-Plex-Token from URL parameters to HTTP headers for all Plex API calls
Impact: Improved security posture, prevents token leakage in server logs and proxy configurations
Files: src/utils/plex.ts (discover endpoint, metadata fetch, RSS generation)

Added Database Fallback for Watchlist Failures

Issue: When Plex API is unavailable or rate-limited, users lose access to their watchlist data
Root Cause: No fallback mechanism when Plex services are temporarily unavailable
Fix: Added database fallback that retrieves existing watchlist items when Plex API fails
Impact: Improved reliability - users maintain access to their watchlists even during Plex outages
Files: src/utils/plex.ts, src/services/plex-watchlist.service.ts

Enhanced GraphQL Rate Limit Handling

Issue: 429 rate limit responses from Plex GraphQL API were not properly identified
Root Cause: Generic error handling didn't distinguish rate limit errors from other failures
Fix: Added explicit 429 status code detection and proper RateLimitError classification
Impact: Better rate limit management and more targeted retry logic
File: src/utils/plex.ts

Improved Data Normalization

Issue: Database fallback could fail with malformed GUID/genre data from different storage formats
Root Cause: Inconsistent data types between JSON strings and arrays in database storage
Fix: Added robust data normalization using existing parseGuids utility and proper type safety
Impact: Reliable data handling across different storage formats, eliminated type casting issues
File: src/utils/plex.ts

Immediate Action Required: Deploy this hotfix immediately to restore Plex functionality
