README Configuration section:
- Organized into logical groups (Core, Admin, Purge, UI, yt-dlp)
- Fixed wrong defaults: admin.enabled (true not false), purge.enabled
(true not false), purge field is max_age_minutes not max_age_hours,
purge.cron is '* * * * *' not '0 3 * * *'
- Removed redundant internal-path vars (DB_PATH, DATA_DIR, OUTPUT_DIR)
that are pre-set in the Dockerfile and shouldn't be changed
- Added missing vars: LOG_LEVEL, UI settings, PRIVACY_MODE, YTDLP
- Added extractor_args usage examples (YAML and env var)
docker-compose files:
- Switched healthcheck from python urllib to curl (already in image)
- Removed stale PURGE__MAX_AGE_HOURS references
- Added commented yt-dlp extractor_args example
- Simplified comments to reflect actual defaults
