Clearer messages when a job or candidate is out of reach, plus a double-submit fix

Honest unavailable states across the platform When you open a link to a job or candidate you can't access, you now see a clear message explaining why — with one click back to the list. Previously you'd get a stuck spinner, a blank page, or an error that disappeared before you could read it.

Candidate form no longer submits twice per click Clicking Save on a candidate create or edit form was occasionally submitting the request twice. It now submits exactly once, as expected.
Interview plan tab no longer shows a false empty state The interview plan tab was showing "No interview plan yet" when the data had simply failed to load. It now shows the right message depending on whether the plan is missing or just unavailable.
Revoked hiring manager access hides action buttons If a hiring manager's assignment was removed, they could still see Approve and Reject buttons that the platform would refuse to act on. Those buttons no longer appear once access has been revoked.
