feat(workflow): split job step from location, model back-and-forth between lab and clinic

Real prosthetic production isn't a one-way pipeline — the work moves
between lab and clinic multiple times. After substructure is produced
the lab hands it to the clinic for a fitting, the clinic approves it
back to the lab, the lab builds the superstructure, hands it back for
a second fitting, the clinic approves again, the lab does cila/bitim,
and finally delivers it to the clinic for handover to the patient.

Previously we only had a single 'advance step' action callable by the
lab, which collapsed all of that into a linear forward push and didn't
capture who physically had the work at any given moment.

DB
  - New jobs.location enum (at_clinic | at_lab, default at_clinic).
  - Existing jobs keep working via a 'location ?? at_lab' fallback in
    code; no manual backfill required for the four test rows.

State machine
  - acceptJobAction (lab): pending → in_progress, currentStep=alt_yapi_prova,
    location=at_lab. Skips the implicit 'olcu' production step now that
    accepting the job means the lab has the impression in hand.
  - handToClinicAction (lab, NEW): at_lab → at_clinic, step stays the
    same. If step is cila_bitim, status becomes 'sent' (final delivery)
    and finance sync fires.
  - approveAtClinicAction (clinic, NEW): at_clinic → at_lab, step
    advances to the next stage so the lab knows what to produce next.
  - markDeliveredAction unchanged — clinic confirms the final handoff.
  - advanceStepAction removed; its single forward push doesn't fit the
    new bidirectional flow.

UI
  - JobActionsPanel now picks the right button from the role + status +
    location matrix:
      * Lab + pending          → 'İşleme Al'
      * Lab + in_progress + at_lab + cila_bitim → 'Cila Bitim — Nihai Teslime Gönder'
      * Lab + in_progress + at_lab + other      → '{stage} Provaya Gönder'
      * Clinic + in_progress + at_clinic → '{stage} Provası Tamam'
      * Clinic + sent          → 'Teslim Aldım'
      * Both + pending         → 'İptal Et'
  - Job detail surfaces a new 'Şu An' info row that resolves to a
    human-readable location ('Klinikte', 'Laboratuvarda', 'Hasta'ya
    teslim edildi', ...) so anyone glancing at the page can tell where
    the work physically is.
