build: configure daemon JVM and improve signing property resolution

- Add `gradle/gradle-daemon-jvm.properties` to specify Java 21 toolchain URLs for various platforms.
- Update `app/build.gradle.kts` to allow signing properties (`KEY_STORE_PASSWORD`, `KEY_ALIAS`, `KEY_PASSWORD`) to be resolved from either environment variables or project properties.
