fix: isolate movie and TV webhook processing to prevent cross-contamination

- Add prefixed batch keys (movie:imdbid, tv:imdbid) to prevent IMDb ID collisions
- Add path existence validation for Radarr webhooks to reject invalid mappings early
- Remove duplicate Radarr webhook handler code
- Add debug scripts for troubleshooting webhook and path mapping issues
- Create corrected .env template with fixed TV_PATHS and SONARR_ROOT_FOLDERS

This fixes the issue where TV path mapping failures caused movie webhooks
to process wrong movies due to shared batch queue corruption.
