ci: build a test APK from any branch on demand

Browse Source 
build-release.yml is tag-driven, builds three platforms and then creates
a release -- none of which is what you want from a feature branch, and
there was otherwise no way to get an installable build out of CI without
cutting one.

workflow_dispatch only, deliberately. The runner has a single slot shared
with two other projects, so an APK on every feature-branch commit would
starve them; dispatch it when you actually want to install something.

Defaults to the R8-minified release build in the debug applicationId slot
rather than a plain debug APK. Minification is where Android releases
have actually broken here (R8 stripping JNI-loaded player and security
classes), and a debug build cannot catch it. Neither variant needs the
real signing key, and both install side by side with a real install.

Builds through scripts/build-android.sh rather than a hand-rolled tauri
invocation, so CI and a developer's machine produce the same thing and
the script's applicationId assertion still runs. Shares the existing
cargo registry cache key -- no fourth copy of the registry on a disk that
has filled before.

### Getting a test APK out of CI
`.gitea/workflows/build-test-apk.yml` builds one from **any branch, on demand**
— run it from Gitea's Actions tab (`workflow_dispatch`) against the ref you want.
It is not a release: nothing is tagged, published, or signed with the real key.
Two variants, both installing into the `com.dtourolle.jellytau.debug` slot:
| Variant | What it is | When |
|---------|-----------|------|
| `side-by-side-release` (default) | R8-minified, exactly what ships, signed with the debug keystore | Almost always — a plain debug build cannot catch R8 stripping JNI-loaded classes, which has broken release APKs here before |
| `debug` | Unminified | When you need readable stack traces |
There is deliberately **no push trigger**: the runner has one slot shared with
two other projects, so building on every feature-branch commit would starve
them. The APK lands as the `jellytau-test-apk` artifact (7-day retention), named
for the branch and short SHA, with its size and SHA256 in the run summary.
