Update android robot package name, target API/Gradle, and localisations

[hardikgarg02]

1. Updated Android robot app's package from org.openbot to org.openbot.app.robot.
2. Updated the robot module's target and compile SDK to API 36 and upgraded the Android Gradle Plugin to 8.9 ( required for Google Play Store listing )
3. Added missing translations for the Web Controller settings section and Web Signaling Server field (web_controller_category, web_signaling_server).

One thing to confirm before merging: google-services.json's oauth_client entries were edited to package_name: "org.openbot.app.robot" while keeping the same certificate_hash values. That's necessary but not sufficient — Google Sign-In needs an actual Android OAuth client registered in Firebase/Google Cloud Console for (org.openbot.app.robot, that SHA-1), and editing the JSON locally doesn't create that registration. Has this been confirmed against the real console (and ideally tested with a live Google Sign-In on a build using the new applicationId)?

Given #535 scrubbed the real Firebase credentials for iOS, could you do the same here? google-services.json still has the real client_id/certificate_hash/mobilesdk_app_id, and googleServices/README.md already has the matching "set up your Firebase project" walkthrough to add a dummy-data note to.

One thing first though: please confirm the org.openbot.app.robot OAuth client registration (from the comment above) actually works with a real Sign-In test before swapping to dummy values, since once it's dummied out there's nothing left to compare against the console.

Everything's addressed, thanks. Good to merge from my side.
