Major refactor for DevExpress Fluent theme compatibility:
- InfoPanel templates now use strongly-typed context (`InfoPanelContext`)
- Unified grid layout with `MgGridWithInfoPanel` wrapper
- CSS updated to use Fluent theme variables and container queries
- App-wide CSS cleanup and formatting improvements
- `.editorconfig` added for modern CSS support
- Improved InfoPanel instance resolution for nested grids
- Codebase is cleaner, more maintainable, and ready for further customization
Introduce reusable MgGridToolbarBase and MgGridToolbarTemplate components, replacing old toolbar implementations. InfoPanel now displays grid captions and includes a toolbar for quick actions. Refactor InfoPanel value rendering for improved DevExpress-like appearance. Update IMgGridBase and related classes to support captions and use new abstractions. Update usings and project structure accordingly.
- Introduce MgEditState enum and expose EditState on IMgGridBase
- Replace event-based syncing state with property-based state
- Redesign MgGridInfoPanel to support both view and edit modes with dynamic DevExpress editors and two-way binding
- Add visual distinction for edit/view modes in info panel
- Replace FruitBankToolbarTemplate with generic MgGridToolbarTemplate; toolbar adapts to grid edit/sync state
- Update all grid usages to use new toolbar
- Improve robustness, error handling, and maintainability throughout grid, info panel, and toolbar code
