fix(workflow): clicking on 'See runs' shows executions from all workflows (#16300)

Fixes: #16229 and #16286

This PR fixes the bug where click on 'See All Runs' button for a
specific workflow was not filtering the runs for that speciific
workflow.

**Reason** : The filter logic in `getFilterFilterableFieldMetadataItems`
was excluding ALL system fields(except field id) from being filterable,
which prevented these essential business relations from being used in
filters.

**Fix** : Added a targeted exception to allow specific system relation
fields (`workflow` and `workflowVersion`) to be filterable, similar to
how the `id` system field is already whitelisted.
