feat(pricing): tooth-based selection, lab-owned pricing, clinic-specific overrides

What changed
  - jobs.teeth (FDI string[]). memberCount becomes a derived field (teeth.length).
    A new TeethChart component renders the full permanent dentition as a
    16-column grid for each arch with click-toggle selection.
  - /jobs/new: removed the price + currency inputs and the manual memberCount
    field. Clinics now pick teeth via the chart; the form blocks submission
    until at least one tooth is selected.
  - createJobAction calls a new calculateJobPrice() helper that walks the
    pricing cascade and writes price + currency on the job server-side. A
    clinic-supplied price hidden field would now be ignored — the field
    isn't even in the schema.

Pricing cascade (calculateJobPrice, lib/appwrite/pricing.ts)
  1. clinic_pricing row matching (lab, clinic, type) with customUnitPrice
     → use that flat unit price.
  2. clinic_pricing row with discountPercent → catalog unitPrice × (1-d).
  3. lab's prosthetics catalog row matching type (not archived).
  4. nothing → price stays null; lab can still set it manually later.

Clinic-specific overrides (clinic_pricing table)
  - Unique on (labTenantId, clinicTenantId, prostheticType) so each
    combination has at most one rule.
  - Row permissions: read by both teams (transparency for clinic), write
    only by lab — clinic can see the discount they're getting but cannot
    edit it.
  - setClinicPricingAction validates an approved connection exists before
    creating/updating, and rejects requests where neither customUnitPrice
    nor discountPercent is set.
  - clearClinicPricingAction wipes a rule (catalog price re-applies).

UI
  - /connections 'Bağlantılarım' table gets a new column showing the active
    pricing rules per counterpart. Lab side has a 'Fiyatlandırma' button
    that opens a dialog (PROSTHETIC_TYPE × customPrice|discountPercent form
    + list of active rules with delete). Clinic side is read-only.
  - Job detail: 'Fiyat' field now shows 'Lab tarafından belirlenecek' when
    null, instead of a literal —. Adds a 'Dişler' info block listing the
    selected FDI numbers.
