fix: resolve build errors and complete dev22 fixes

- Fixed syntax error in main.go formatBackground section
- Added formatContainer widget for format selection in Convert module
- Fixed forward declaration issues for updateDVDOptions and buildCommandPreview
- Added GPUVendor() method to sysinfo.HardwareInfo for GPU detection
- Implemented automatic GPU detection for hardware encoding (auto mode)
- Fixed JobTypeFilters -> JobTypeFilter naming inconsistency in queue.go
- Added proper JobType specifications to all queue constants
- Removed duplicate/conflicting types.go file

This fixes all compilation errors and completes the dev22 release readiness.
