Hiding or showing a calendar on the web sets enabled=false + sidebar_hidden
server-side, so the server stops returning that calendar's events entirely.
The app only reconciled these per-calendar flags when the filter sheet or the
accounts screen happened to be opened — never on launch, resume or the
periodic pull. So a calendar re-enabled on the web stayed invisible (still
banished locally, and its events weren't in the cache) until a manual sync or
relaunch — the "hide it on the web and the app won't bring it back" bug.
Add CalendarStore.reconcileCalendarVisibility(api:) which pulls the account
lists, updates the banished set from the server's sidebar_hidden flags, and
returns whether anything changed. CalendarHostView now runs it (via
syncFromServer) on launch, on scenePhase .active, in the periodic loop, and on
manual sync — forcing a refetch when the set changed so a re-enabled calendar's
events actually reappear without user intervention.
