Initial commit: TVH2Jellyfin application

A Docker-based Python application that transfers completed recordings
from TVHeadend to Jellyfin media storage via SCP.

Features:
- Monitors TVHeadend for completed recordings via JSON API
- Transfers files via SCP with SSH key authentication
- Organizes files by show name
- Deletes recordings from TVHeadend after successful transfer
- Tracks transferred files to avoid duplicates
- Dry run mode for testing without making changes
