* Fix#5602: Ensure controller status update triggers update_time
Rework and fix the logic of #5602 query split. Initial implementation failed to update controller status within `server_controller` as `w.Update` did not trigger `update_time` if `address` or `description` were not updated. Now using `w.Exec` with `updateController` query to always set `update_time` to `now()`.
Additional Notes:
- Updated `repository_controller` tests to verify `update_time` updates even when controller values don't change.
- Added `cleanupFunc` to test cases to remove inserted controllers after each test.
- Verified via `boundary dev` that `worker.upstreamDialerFunc` errors are not present.
