Prepare Nova 1.0.7 Google TV compatibility release

[papi-ux]

Summary

• Bump the next release metadata to 1.0.7 / 22 for a Google TV compatibility release.
• Add armeabi-v7a to the default release ABI split set so Chromecast with Google TV, Google TV Streamer, and other 32-bit ARM Android TV devices get a public APK.
• Update the release workflow to name, upload, and verify Nova-Android-armeabi-v7a.apk plus its checksum alongside the existing ARM64 and x86_64 assets.
• Recognize the Steam Controller 2026 Bluetooth keyboard/mouse HID shape reported by Google TV (0x28de:0x1303) as controller input so Nova advertises a host gamepad and routes compatible D-pad/button events through the controller path.
• Refresh README, changelog, Fastlane changelog, and public-docs checks for the new APK and Steam Controller compatibility notes.
• Add regression guards around the Gradle default ABI list, release workflow asset verification, and Steam Controller HID detection.

Verification

• Red check first: ./gradlew -PnovaAbis=x86_64 :app:testNonRoot_gameDebugUnitTest --tests com.papi.nova.ui.NovaComposeBuildConfigurationTest --console=plain failed before implementation because armeabi-v7a was missing from Gradle/workflow expectations.
• Red check first: Steam Controller HID tests failed before implementation because Valve 0x28de:0x1303 keyboard/mouse input was not accepted as controller input.
• Captured Google TV dumpsys input evidence showing Steam Ctrl (BT) FXA9960600962 as vendor 0x28de, product 0x1303, sources KEYBOARD | MOUSE | STYLUS, keyboard type 2, with no GAMEPAD or JOYSTICK source.

Notes

• Android exposes this Steam Controller Bluetooth mode as keyboard/mouse rather than a full standard gamepad source, so this PR makes the compatibility path explicit and scoped. The right trackpad remains mouse-like input, and full Steam Input profile behavior still depends on what Android exposes or what the host handles.
