Converted AppBranding, DataSourceCard, CodeExplanationDialog, ComponentPalette, and CanvasRenderer from TSX to JSON-based architecture.
Changes:
- Created JSON definitions in src/components/json-definitions/
- Created TypeScript interfaces in src/lib/json-ui/interfaces/
- Added exports to src/lib/json-ui/json-components.ts
- Updated json-components-registry.json with 5 new components
- Updated registry statistics (total: 347, molecules: 50, jsonCompatible: 124)
All components use createJsonComponent for pure JSON rendering without hooks.
Build passes with no errors.
