Fix all Sonarr webhooks: Force targeted processing for single episodes

- Extend episodeFile extraction to ALL webhook types (Download, Rename, Upgrade)
- Force targeted mode when episodes_data has ≤3 episodes to prevent full series processing
- Add debug logging to track episode extraction and processing mode decisions
- Prevents processing 177 episodes when only 1-3 episodes are involved
- Applies to imports, renames, and upgrades - not just renames
- Version bump to 2.0.12

This ensures that single episode operations (most common) only process the specific
episode(s) involved instead of scanning the entire series.
