#572 president-only focused view for executive meetings

User asked that when the President (`executive_ceo` role) logs into
the Meetings page he sees a clean "presentation" layout: just the
schedule table, an analog clock plus the weekday/date of the
schedule, and nothing else. The Manage / Notifications / Audit /
PDF tabs and the PDF-export shortcut button are noisy for him and
must disappear — but his backend permissions stay intact.

Changes (frontend only — backend role gates untouched):
- New component `components/executive-meetings/analog-clock.tsx`:
  small SVG analog clock (hour/minute/second hands, navy + gold),
  ticks every second, ~44px default.
- New inner `PresidentClockBar` component in `executive-meetings.tsx`:
  renders the analog clock + weekday + **digital time** (ticking
  per second, localized) + selected schedule date in one block.
- `pages/executive-meetings.tsx`:
  - Derived `isPresidentView` from the `/me` roles: true iff
    `executive_ceo` is present AND the user is NOT also `admin`
    or `executive_office_manager` (admins keep full UI).
  - Effect forces `section = "schedule"` whenever
    `isPresidentView` becomes true, so the president can never
    land on a now-hidden tab.
  - Hides the header PDF-shortcut button and the entire SECTIONS
    tab list when `isPresidentView`. The `#em-toolbar-portal` is
    kept so the date picker still mounts.
  - `ScheduleSection` accepts two new optional props:
    `isPresidentView` and `lang`. When `isPresidentView` is on,
    the toolbar renders the AnalogClock next to a label showing
    `formatWeekday(date, lang, "long")` and `formatDate(date, lang)`
    (e.g. "Sunday · May 17, 2026" / "الأحد · 17 مايو 2026"). The
    label updates immediately when the date input changes.
  - Edit-mode toggle stays gated on `canMutate`, so the president
    (who has canMutate) still gets the inline-edit pencil if he
    wants it.

Out of scope: backend role changes, applying the focused view to
other roles, manual presentation-mode toggle. Verified via tsc
(only the pre-existing `use-push-subscription` error remains).
