fix(android): align JoyStick Gradle wrapper with root (8.13)

JoyStick still used Gradle 8.2 while resolving AGP 8.13 deps; Gradle 8.2
could not instrument bcprov 1.79 (Java 21). Copy wrapper jar and bump
distribution URL to match the root project.

-GitHub Actions on **`main`** / **`master`** run **[`.github/workflows/ci.yml`](.github/workflows/ci.yml)** (Linux containers, macOS, Windows, Android, optional log checks). The **Android** job uses **JDK 21** in CI so Gradle can handle current dependency bytecode (AGP 8.13 pulls libraries with multi-release JARs). **[`build.yml`](.github/workflows/build.yml)** (ETLBuild) runs on tagged releases, a weekly schedule, and manual dispatch. **[`snapcraft.yml`](.github/workflows/snapcraft.yml)** builds the upstream **[etlegacy-snap](https://github.com/etlegacy/etlegacy-snap)** tree after ETLBuild completes; it expects **`SNAPCRAFT_STORE_CREDENTIALS`** where publishing is desired.
