Add configurable TV season directory naming

Features:
- TV_SEASON_DIR_FORMAT: Configurable season folder creation (Season {season:02d})
- TV_SEASON_DIR_PATTERN: Configurable season folder detection (season )
- Support for different naming conventions (Season 01, S01, Season01, etc.)
- Updated .env.template with TV configuration examples

Fixes hardcoded 'Season ' patterns for better flexibility
