feat: implement Auto-Tagging system

[TheNightShift-nsfw]

This PR introduces a comprehensive Auto-Tagging system for XBVR.

Features:

• Actor trait tagging: Automatically tag scenes with actor age, height, nationality, ethnicity, hair/eye color, and cup size.
• Video quality tagging: Tags for resolution (4K, 8K, etc.) and format (180, 360, Flat).
• Scene attribute tagging: Tags for duration categories and interracial status.
• Schedule integration: New 'Auto Tags' tab in Task Schedules to configure and automate these tasks.
• System Tag management: System-generated tags are marked as such, allowing for easy reset without affecting manual tags.

Minor Fixes:

• Improved DLNA stability by handling missing icons gracefully.

Closes #2129 (if applicable, based on recent deps update context).
