refactor: add wx-svelte-grid Cell type for database cells

Phase 2.2: Add proper type definitions for wx-svelte-grid
- Created Cell interface export in wx-svelte-grid declarations
- Updated all 9 database cell components to use Cell type
- Removed custom Props interfaces with loose IRow typing
- Improved IntelliSense support for grid component props
