Commit incremental progress

- Current state: 3 modules partially/fully extracted
- upscale_module.go: showUpscaleView + AI helpers migrated successfully
- Build syntax: ✅ Clean
- Build failing due to unrelated Fyne API issue in internal/ui/queueview.go
- Ready for next incremental extraction steps
