fix: add timeout guards to bootstrap initialization

Add AUTH_INIT_TIMEOUT (10s) to bootstrapStore's blocking until() waits
for Firebase auth and user login, preventing indefinite hangs if auth
initialization stalls. Wrap cloud init (remote config + telemetry) in
try-catch so the app continues loading even if cloud services fail.
