feat: migrate ConflictDetailsDialog and DataBindingDesigner to JSON

Converts two additional components to JSON architecture with custom hooks:
- ConflictDetailsDialog: Dialog component with conflict diff analysis
- DataBindingDesigner: Designer for data binding configuration

Includes:
- JSON definitions in src/components/json-definitions/
- Custom hooks (useConflictDetailsDialog, useDataBindingDesigner)
- TypeScript interfaces for type safety
- Registry updates and exports

All tests passing, build clean (0 audit issues).
