EXTRA Will Call Signer

- Smoother kiosk order handling: tablet-sent orders are selected automatically, with a new option to remove all orders at once.
- Better order lookup: improved kiosk search and barcode-based invoice lookup.
- A faster signing flow: start signing from order details, go straight to the signature task when it’s the only task, and clear the invoice search after signing.
- Small UX fixes: show or hide the login password, close the camera from the scan view, and see the logged-in location.
