Fix job details popover sticking after cancel/delete (#6930)

## Summary
- close the job details popover when its job disappears or timers fire
after list changes, and clear hover timers on unmount
- emit an explicit details-leave on cancel/delete clicks so the popover
closes even if hover-out never fires
