- Added "Use currently selected API configuration" option in Modes panel
- Similar to existing functionality in Prompts settings for enhance/condense
- Users can now select specific API configs for each mode or use the current one
- Updated translation keys for new feature
- Leverages existing modeApiConfigs state management
