Improve preset UX and finalize 800x600 UI scaling

UI Scaling Improvements:
- Reduce module tiles from 160x80 to 150x65
- Reduce title from 20 to 18
- Reduce queue tile from 140x50 to 120x40
- Reduce category labels to 12px
- Reduce padding from 8 to 4px
- Remove scrolling, everything fits in 800x600

Preset UX Improvements:
- Move "Manual" to bottom of all preset dropdowns
- Default bitrate preset: "2.5 Mbps - Medium Quality"
- Default target size: "100MB"
- Manual input fields hidden by default
- Show manual fields only when "Manual" selected

Encoding Preset Order:
- Reverse order: veryslow first, ultrafast last
- Better quality options now appear first
- Applied to both simple and advanced mode
