feat(jobs/new): live price quote with discount breakdown for the clinic

Clinics couldn't see what an order would cost them before publishing.
Added a server-priced quote box that updates as the lab, prosthetic type
and tooth selection change. Three rendered states:

  1. Discounted (custom unit price or discountPercent):
       Katalog (4 × 1.500 ₺)      6.000 ₺
       Klinik indirimi (%15)       -900 ₺
       ──────────────────────
       Toplam                    5.100 ₺

  2. Plain catalog match (no clinic override):
       4 × 1.500 ₺               6.000 ₺
       'Katalog fiyatı uygulanıyor'

  3. No catalog row for the chosen type:
       'Fiyat işe başlanırken laboratuvar tarafından belirlenecek'

Bits to make this work
  - calculateJobPrice now returns catalogUnitPrice, catalogTotal, savings
    and teethCount alongside the final amount, so the client can render
    a breakdown without reaching for any other table.
  - POST /api/pricing/quote endpoint guards on clinic kind + an approved
    connection before exposing pricing — no leaking catalog data to
    unconnected clinics, and no per-lab discount snooping.
  - NewJobForm's lab and prosthetic Selects became controlled (hidden
    inputs mirror state to the form action), and a debounced effect
    (250ms) re-fetches the quote when any of {lab, type, teeth.length}
    changes. AbortController cancels in-flight requests when inputs change
    again.
