Task #701: توحيد نموذج الحجز الداخلي مع نموذج الرابط العام

- Extended internal BookingDialog (artifacts/tx-os/src/pages/protocol.tsx) to match
  the public booking form: requester name, phone, room, department, meeting title,
  meeting type toggle (داخلي / مع جهة خارجية), conditional entity name (external only),
  expected attendee count, purpose, from/to, key attendees in two columns
  (من الهيئة / خارج الهيئة) with add/remove name+position rows, and notes.
- Edit mode prefills all new fields from the booking; click-to-book initialStart
  behavior unchanged.
- api-server (artifacts/api-server/src/routes/protocol.ts): bookingCreateSchema and
  bookingPatchSchema now accept requesterPhone, requesterOrg, department, meetingType,
  purpose, keyAttendees; POST/PATCH /protocol/bookings persist them. requesterOrg is
  nulled whenever effective meetingType is internal (create and patch).
- Added i18n keys protocol.bookings.form.{name,position,addRow,removeRow} (ar/en);
  all other labels reuse existing protocol.bookings keys.
- Verified: tsc clean for changed files (push.ts / executive-meetings.ts errors are
  pre-existing and unrelated); API workflow restarted and serving; architect review PASS.
- Note: entity name (اسم الجهة) is not enforced as required for external meetings on
  the internal endpoint (unlike the strict public endpoint) — internal staff keep
  flexibility; can be tightened later if requested.
