feat: Complete manager migration with conflict detection integration

This completes the integration of ComfyUI Manager migration features with enhanced conflict detection system. Key changes include:

## Manager Migration & Conflict Detection
- Integrated PR #4637 (4-state manager restart workflow) with PR #4654 (comprehensive conflict detection)
- Fixed conflict detection to properly check `latest_version` fields for registry API compatibility
- Added conflict detection to PackCardFooter and InfoPanelHeader for comprehensive warning coverage
- Merged missing English locale translations from main branch with proper conflict resolution

## Bug Fixes
- Fixed double API path issue (`/api/v2/v2/`) in manager service routes
- Corrected PackUpdateButton payload structure and service method calls
- Enhanced conflict detection system to handle both installed and registry package structures

## Technical Improvements
- Updated conflict detection composable to handle both installed and registry package structures
- Enhanced manager service with proper error handling and route corrections
- Improved type safety across manager components with proper TypeScript definitions
