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.

 ## Versioning and Delivery
 
-`config/version` in `project.godot` is the single version source (currently `0.8.0`). Releases are tagged `v<version>`; the CI pipeline builds and publishes the standard artifacts plus the optional Desktop HQ zip. Version bumps follow [Semantic Versioning](https://semver.org/). See [`docs/RELEASING.md`](docs/RELEASING.md) and [`README.md`](README.md) for commands.
