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.

-The single source of truth for the version is `config/version` in `project.godot` (currently `0.8.0`). Each release is tagged in git as `v<version>` (e.g. `v0.6.0`). The `0.x` series is pre-1.0, so MINOR bumps may introduce breaking changes while the prototype is still stabilizing. `tools/build_releases.sh` and `tools/publish_release.sh` read the version from `project.godot`, so bumping it there is the only required step before a release. The full bump checklist lives in [`RELEASING.md`](RELEASING.md).
