#598 global "other apps" bottom dock + remove duplicate #596 gear

New shared component `artifacts/tx-os/src/components/app-dock.tsx`:
takes a `currentSlug` prop, pulls the apps list from the same
`useListApps()` query Home uses, filters out the current app and any
inactive ones, and renders a floating centered pill near the bottom
with one circular tinted button per remaining app. Reuses Home's
`resolveIcon(name)` pattern (Lucide string -> component, falls back to
Grid2X2) and Home's openApp logic (internal -> setLocation, external
_tab -> window.open, external_iframe -> /embedded/:id). Renders
nothing when fewer than 1 other apps are available. Hidden in print,
respects safe-area-inset-bottom, scrollable on narrow widths.

Mounted on every app page except Home:
- executive-meetings.tsx (currentSlug="executive-meetings", matches
  seed slug; hidden when isFullscreen is true so the schedule fills
  the screen unobstructed).
- services.tsx (currentSlug="services")
- notes.tsx (currentSlug="notes")
- orders-incoming.tsx (currentSlug="orders-incoming" — not a built-in
  app slug, so all apps show, which is the right UX since incoming
  inbox is reached via the topbar, not the home grid).
- admin.tsx (currentSlug="admin")

Removed the two gear/back-arrow blocks added by #596 in
executive-meetings.tsx (test ids em-president-settings,
em-president-back-to-schedule) — the dock now provides cross-app
navigation including Admin/Settings. The L902 force-schedule effect
that snaps the president back to the schedule section outside of
schedule|settings is left in place; it still gates the hidden
Manage / Audit tabs.

Verified `pnpm --filter @workspace/tx-os exec tsc --noEmit` clean.
No backend, no new translations, Home untouched.
