feat(nav): single Calendar menu — hide Appointments resource from sidebar

AppointmentResource::\$shouldRegisterNavigation = false so only
CalendarBoard shows in the sidebar as "Calendar". The board already
has a "Listă" view-mode button alongside Zi/Săpt/Lună/Custom, so both
use cases are covered from a single entry. CRUD routes
(/app/appointments/create, /{id}/edit) stay accessible from the
board's click handlers.
