Add your language: translations are now possible

[HMAKT99]

All UI strings live in a single file: app/src/main/res/values/strings.xml (~60 strings).

To add a language:

1. Create app/src/main/res/values-<code>/strings.xml (e.g. values-de, values-es, values-hi).
2. Translate the strings — please keep the safety wording faithful, especially disclaimer_body, check_notice, and assist_safety_note (this is a hearing-related app; the 'not a medical device' framing must survive translation).
3. Build with ./gradlew assembleDebug and switch your device language to verify.

No Kotlin knowledge needed. One language per PR is perfect.
