fix(fdroid): Fix F-Droid build configuration

- Use specific commit SHA (381515a) instead of branch reference
- Change gradle target from 'yes' to 'release' build variant
- Use 'npm ci' with legacy-peer-deps for deterministic builds
- Add nodejs and npm to sudo dependencies
- Remove custom build step (gradle handles Android build)
