feat: migrate SchemaEditor organisms to JSON

Completed migration of all 6 SchemaEditor organisms from TSX to JSON:
- SchemaEditorCanvas
- SchemaEditorLayout
- SchemaEditorPropertiesPanel
- SchemaEditorSidebar
- SchemaEditorStatusBar
- SchemaEditorToolbar

Changes:
- Created JSON definitions in src/components/json-definitions/
- Created TypeScript interfaces in src/lib/json-ui/interfaces/
- Exported from src/lib/json-ui/json-components.ts using createJsonComponent
- Updated src/components/organisms/index.ts to import from json-components
- Deleted 6 TSX files from src/components/organisms/
- Updated interfaces/index.ts to export new interface files

Build: ✓ passing
TSX files deleted: 6
JSON definitions created: 6
Interfaces created: 6
