Clearer kiosk prompts and simpler user management

What's New

• Clearer prompts when workers leave early. If a worker taps End Shift significantly before their scheduled end time, the kiosk now asks whether they're leaving now or forgot to end earlier. Picking forgot to end flags the shift for your review so you can set the right end time.

What's Improved

• Simpler user management. Admins no longer have a Show Deleted toggle. To remove someone from the app, deactivate them.

• More reliable kiosk status. Kiosks now ping the server every couple of minutes so you'll know when one actually goes offline, without false alerts during quiet periods.
