feat(jobs): clinic-side 'Düzeltme İste' (revision request) flow

Up to now the only thing a clinic could do on a prova was approve it.
If the casting didn't fit there was no way to bounce the case back to
the lab short of cancelling the whole thing. Real-world flow needs a
'try again, this is what's wrong' lever, so:

  - requestRevisionAction (clinic only): pre-conditions
    in_progress + at_clinic + currentStep set; flips location → at_lab
    while leaving currentStep untouched so the same prova stage repeats
    after the lab redoes the work. Requires a note (the lab can't fix
    what it doesn't know is broken) — appended to job_status_history
    with a '[Düzeltme talebi]' prefix and surfaced to the lab via
    notification.
  - JobActionsPanel: when the clinic side sees a prova (in_progress +
    at_clinic) it now shows two buttons — Onayla as before, plus
    Düzeltme İste (variant=destructive). The dialog requires a note
    before submit.
