Send Control App

Improvements to offline check-in syncing. • Check-ins made offline now sync reliably. • Syncing now starts on its own: when the signal comes back, when leaving offline mode, and periodically, with no need to tap "Retry". • New sync diagnostics screen: it shows how many check-ins went through, which ones didn't and why, with a suggested fix for each case and the option to copy the report for support. • The sync indicator now shows a partial state, for when some check-ins go through and others stay pending. • Check-ins the controller can never resolve are no longer retried indefinitely. • Fixed the time recorded for offline entries. • A network failure no longer interrupts syncing. • Entries that require biometric verification are now flagged as pending validation instead of showing a generic error. • Downloaded passes appear as soon as they sync, with no need to restart the app. • Visual fixes in the top bar: the greeting and icons no longer overflow on narrow screens or with large text.
