refactor: remove unused UI and execution configuration

Remove unused configuration options that were not consumed by the UI:

- Remove UI configuration (UI_FONT_FAMILY, UI_FONT_SIZE, UI_PRODUCTION_ID_INPUT_WIDTH)
  - No UI components were using these settings
  - Settings page had no inputs for these options

- Remove execution configuration (EXECUTION_DRYRUN)
  - Dry run mode is controlled by Cleaner page UI toggle
  - State is managed via sessionStorage, not config file

Files modified:
- src/main/types/settings.types.ts: Remove UiConfig and ExecutionConfig interfaces
- src/main/services/config/config-manager.ts: Remove config read/write logic
- src/main/ipc/settings-handler.ts: Remove filtered fields
