Fix normal radio report submission

The radio button was connected only to the emergency hold handlers, so a
normal Send request never reached _submit. Connect pressed for non-emergency
calls while keeping hold-to-confirm exclusive to emergencies, and add tests
for click, short-hold rejection and full emergency hold. Headless 249/249,
Python 94/94.
