In executive-meetings.tsx, the floating exit-fullscreen control was
a pill (`gap-1.5 px-3 py-1.5`) showing both a Minimize2 arrow and
the Arabic/English label "الخروج من ملء الشاشة" / "Exit fullscreen".
User asked for icon only.
Changes:
- Removed the `<span>{t(...)}</span>` label.
- Swapped pill classes for a circular icon button: `inline-flex
items-center justify-center rounded-full bg-[#0B1E3F] text-white
w-9 h-9 shadow-lg hover:bg-[#0B1E3F]/90 print:hidden`, keeping the
same `fixed top-3 end-3 z-50` positioning.
- Bumped the icon to `w-5 h-5` so it reads cleanly on its own.
- Added a `title` attribute (hover tooltip) mirroring the existing
`aria-label` — screen readers + mouse users still get the
localised "exit fullscreen" affordance.
- `data-testid="em-fullscreen-exit"` untouched, so existing tests
keep passing.
- No translation key changes; no change to the enter-fullscreen
toolbar button at L2958.
Verified `pnpm --filter @workspace/tx-os exec tsc --noEmit` clean.
