v0.1.6: validate the session on open, not mid-map

A stale/expired token doesn't 401 — /api/User returns an empty body, so
getUserDetail() resolved to undefined without throwing and the launch probe set
signedIn anyway. The dead session then only surfaced when the map/kiosk calls
ran. Now the launch check requires real user data (PersonalPhone/Email); if it's
missing it clears the token and shows the login screen at open.
