Users can now choose how many records to display per page in the MassData grid (100, 1,000, 10,000, 100,000, or all). The backend and API client are updated to support nullable skip/take parameters, allowing "all" records to be fetched when desired. The pager and page count calculations are updated to reflect the selected page size, and the pager is hidden if only one page exists. Additional UI and CSS changes provide a combo box for page size selection. The API controller now treats take <= 0 as "no limit."
Introduces MassData management to backend and Blazor frontend:
- Adds API endpoint for MassData count and paging
- Updates repository and controller for count support
- Implements MediatR query/handler for count
- Adds Blazor page and grid for viewing/editing MassData
- Registers MassDataApiClient and integrates with DI
- Supports paging, upsert, and UI feedback in grid
Introduce MassData feature with new API endpoints for querying and upserting records by customer name. Add DTOs, AutoMapper profile, MediatR CQRS handlers, repository pattern, and MassDataDbContext. Register new services in DI and add MassDataConnection to configuration. Upsert uses stored procedure. Enables full CRUD for Massdata via dedicated API.
