fix(web): name the local calendar "Compass" to match the server (#2171)

The client synthesized the anonymous/offline calendar as "Local" while the
backend ensureLocalCalendar names it "Compass", so the sidebar row renamed
itself from "Local" to "Compass" the moment an anonymous user signed up.
Align the client on "Compass". isPrimary is intentionally left as-is (the
client sentinel is primary because it is the only calendar; the server sets
it false so a connected Google primary keeps that role).
