v0.4.0: Anonymous Mode + zone-location mirror; free check-in on any zone
Some checks failed
build-apk / build (push) Failing after 1h56m52s
Details

Anonymous Mode — "Park without signing in" on the login screen (with a popup of
what works vs needs a login). Anonymous users browse parking areas from our
mirror, see labels, and start free check-in timers; paying, sessions, and
account screens prompt to sign in. AuthContext gains an 'anonymous' status +
enterAnonymous/requireLogin.

Zone mirror — server gains a `zones` table + public GET /api/zones and admin
POST /api/zones/sync. Signed-in admins push the zones they pull (authed) from
ParkSmarter after each map search, so anonymous users can read areas without a
ParkSmarter login. Map/Scan read the mirror when anonymous.

Also: the free "Check in" button is now always available with a 2h/3h/4h picker
(no longer gated on a prior label) — fixes "couldn't start a timer on a free
zone". CORS probe confirmed ParkSmarter allows any origin but only Content-Type,
so a future PWA can't auth to it — the mirror is what makes anonymous browsing
(and a PWA) possible.
