fix: column sort in experiments table

[shivoomiess]

Description

This PR fixes the issue of column sorting not working properly in the Experiments Table.

Motivation and Context

The column sorting feature in the Experiments Table was not functioning as expected, leading to a less intuitive and potentially confusing user experience. This fix is necessary to ensure that users can sort data in a logical and predictable manner, improving the usability of the table.

Changes

1. Debugging capabilities were added to React and the local backend to better facilitate future troubleshooting efforts.
2. The backend's dev script was updated to include the --inspect flag, allowing for easier debugging.
3. The ExperimentDataSource.ts file was updated to include a map of fields that can be sorted. This provides explicit control over which columns can have their sorting functionality enabled.
4. The experiments.cy.ts e2e test file was updated to include tests for the sorting functionality of each column in the visit table. This ensures that our sorting feature works as expected in the future.

Pull request overview

This PR fixes broken column sorting in the Experiments table by introducing a typed sort-field enum end-to-end (frontend → GraphQL → backend → DB column mapping) and updating UI/test behavior around sortable vs non-sortable columns.

Changes:

• Replaced the experiments sortField GraphQL argument from String to a dedicated ExperimentTableSortField enum and threaded the type through resolvers/queries/datasources.
• Added explicit mappings for sortable fields (UI column field → GraphQL enum → DB column) and disabled sorting for columns not supported at the DB layer.
• Updated Cypress e2e coverage around experiments table sorting interactions and added local debugging configuration/script changes.
