Style profiler filter menu to match result grid menu

## Summary
The profiler's filter menu styling is inconsistent with the result grid menu styling.
Profiler:

Result grid:

## Requested change
Update the profiler filter menu UI so it is styled consistently with the result grid's menu. We should retain column name thought.

## Expected outcome
- Visual style, spacing, hover/focus states, and typography should match the result grid menu pattern.
- No behavior changes are required; this is a styling consistency update.

## Notes
Please use the existing area label for profiler work (no new label needed).

Start by locating the profiler filter menu and the result grid menu in the TypeScript UI code, then compare the existing menu styling and states. Update the profiler menu to match the result grid's spacing, typography, hover, and focus treatment while retaining the column name; done means the two menus are visually consistent without behavior changes.
