Add job queue system with batch processing support

Implements a comprehensive job queue system for batch video processing:
- Job queue with priority-based processing
- Queue persistence (saves/restores across app restarts)
- Pause/resume/cancel individual jobs
- Real-time progress tracking
- Queue viewer UI with job management controls
- Clickable queue tile on main menu showing completed/total
- "View Queue" button in convert module

Batch processing features:
- Drag multiple video files to convert tile → auto-add to queue
- Drag folders → recursively scans and adds all videos
- Batch add confirmation dialog
- Supports 14 common video formats

Convert module improvements:
- "Add to Queue" button for queuing single conversions
- "CONVERT NOW" button (renamed for clarity)
- "View Queue" button for quick queue access

Technical implementation:
- internal/queue package with job management
- Job executor with FFmpeg integration
- Progress callbacks for live updates
- Tappable widget component for clickable UI elements

WIP: Queue system functional, tabs feature pending
