#596 صلاحية الرئيس: حذف بحث الاجتماعات + زر الإعدادات

Two changes to artifacts/tx-os/src/pages/executive-meetings.tsx,
both gated on `isPresidentView` so non-president users are unaffected.

1. Schedule search hidden for the President
   - Wrapped <SearchToggle> in ScheduleSection (L2945) in
     {!isPresidentView && (...)}.
   - Kept searchQuery state + meetingMatchesSearch wiring intact:
     when query is "" the filter is a no-op, so the President sees
     the full day's meetings, and the box reappears for anyone else.

2. Gear button so the President can reach Settings (font controls)
   - Added an icon-only gear button (SettingsIcon, lucide-react —
     already imported) in the header right-side block (L1113),
     visible only when isPresidentView && section === "schedule".
     data-testid="em-president-settings".
   - Added an icon+label "back to schedule" button (ArrowRight for
     RTL / ArrowLeft for LTR) shown when isPresidentView &&
     section === "settings". data-testid="em-president-back-to-schedule".
   - Relaxed the force-schedule effect (L966) so the President is
     only redirected when section is neither "schedule" nor
     "settings" — otherwise the gear tap would bounce back instantly.
   - Sub-nav stays hidden (`!isPresidentView` on the SECTIONS map
     is unchanged). Gear is the only entry point.
   - No backend, no new i18n keys (reuses
     executiveMeetings.nav.settings / .schedule).
   - FontSettingsSection already renders for canRead users, and
     canEditGlobalFontSettings stays as the API reports it — no
     extra client-side gate.

`pnpm --filter @workspace/tx-os exec tsc --noEmit` clean.
