[Feature Request] Sortable columns on workflow list page

Is your feature request related to a problem?

The workflow list is currently ordered by status group (Running first, then Completed), then by start time descending within each group. There is no way to sort by any column (Start time, End time, Workflow Type, etc.) by clicking the column headers.

Describe the solution you'd like

Clickable column headers that toggle ascending/descending sort order, similar to standard table UIs. At minimum: Start time, End time, Status.

Describe alternatives you've considered

• tctl / temporal CLI with --filter + sort via workflow list
• • Temporal Web API — query directly if needed in a script
• • • Saved Views — can filter by type/status but still no sort control

Additional context

Sorting by start time globally (regardless of status) is useful when debugging workflows that were triggered in sequence — you want to see execution order, not status grouping.

Start at the workflow list page and trace how its current status grouping and start-time ordering are implemented. Review the list's data and table entry points, then add sorting for Start time, End time, and Status with ascending/descending header toggles; done means the list can be sorted globally rather than only by status group.
