fix(web): reset job list UI on restart failure (#499)

* fix(web): reset job list UI on restart failure

The restartJob() catch handler was missing a loadJobs() call, so the
job row stayed in a stale highlighted state after a failed restart
attempt. Add loadJobs() to match the success path behavior.

Closes #485

* refactor: use .finally() for loadJobs() instead of duplicating

Move loadJobs() to a .finally() block so it runs on both success and
failure without duplication.
