#322 Simplify Add/Edit Meeting dialog and attendee rows

Trim the إضافة اجتماع / تعديل اجتماع dialog and attendee rows in
artifacts/tx-os/src/pages/executive-meetings.tsx down to the fields
the user actually fills in.

MeetingFormDialog
- Removed FormRows: titleEn, location, meetingUrl, platform, status,
  isHighlighted, notes.
- Kept titleAr, meetingDate, dailyNumber, startTime, endTime, and
  the attendees section.
- Save validation now only requires titleAr.
- titleEn is always mirrored from titleAr on save. The English input
  is gone, so there is no way to keep an independent English title;
  always syncing avoids leaving a stale server-side titleEn after the
  Arabic title is edited. The API still receives a non-empty titleEn
  so POST validation (min length 1) is satisfied.
- MeetingFormState, emptyMeetingForm, and openEdit are unchanged so
  hidden fields (location, notes, platform, status, isHighlighted,
  meetingUrl) round-trip through the save body and existing data is
  preserved on edit.

SortableAttendeeRow
- Removed the parenthesized title Input and the
  internal/virtual/external Select.
- Dropped the now-unused onChangeTitle / onChangeAttendanceType
  props from the component signature and the call site.
- Existing attendees keep their stored title and attendanceType;
  new attendees added via addAttendee continue to default to
  title=null and attendanceType="internal" so the schedule's
  grouping keeps working.

Cleanup
- Removed the now-unused Textarea import (only the notes field
  used it). Switch is still imported because it is used elsewhere
  in the file.

Code review found two issues that were fixed before completion:
- Mirroring made deterministic (always sync) instead of
  blank-only fallback.
- Orphaned Textarea import removed.

No DB schema, API, schedule view, Manage list, audit, notifications,
or translation changes.
