Detail pages (clients, yachts, companies, berths, invoices, expenses)
now push their entity name + a back-button toggle to the mobile
topbar via useMobileChrome, replacing the URL UUID fallback that was
rendering before.
Supporting changes:
- useMobileChrome() no longer throws when called outside the
MobileLayoutProvider — desktop-tree consumers get a no-op
setChrome so callers don't have to branch on shell type.
- setChrome is now stable across renders (useCallback) so callers'
useEffect dependency arrays don't infinite-loop.
- DetailPageShell now also pushes its entityName + cleans up on
unmount, and hides its desktop-only sticky header on mobile so it
doesn't double up with the topbar (no current callers, prep for
Phase 4 migration).
