Calendar, contacts, files and settings still drew the left navigation
rail under Mountain View, so moving away from mail switched to the
default frame. They now show the Mountain View top bar too, without the
mail search and the menu button, which only make sense in mail.
Only the mail shell updated document.title, so every other surface sat at the
static value the root layout renders: the tab could not tell you where you
were, and on a multi-account setup it could not tell you whose mailbox you
were in either.
Each surface now sets "<screen> - <account> - <app>" through the shared
useDocumentTitle hook. Labels reuse the sidebar navigation translations, so
the tab and the rail never disagree about what a screen is called - no new
translation keys.

Docker/Playwright regression for the cross-account id-namespacing fix: log in
two accounts, enable the Pro shell, deselect a calendar, switch the active
account, and assert the deselection survives (it reset before the fix because
the previously-active account's ids flipped raw<->namespaced on the switch).
Adds the minimal test hooks: data-testid on calendar sidebar rows
(calendar-item + data-calendar-name/-visible), the settings tab buttons
(settings-tab-<id>), and a testId passthrough on ToggleSwitch used for the Pro
interface toggle. New app helpers: openCalendar (in-app nav, since a hard goto
to a deep link bounces to login), calendarRows, enableProInterface (toggles via
the settings UI - the app doesn't survive a hard reload and seeding proInterface
before login destabilises the add-account popover).
Verified green in the dockerized Stalwart harness.
