Update deps

[w568w]

This PR:

• bumps Android NDK, Gradle, Kotlin to their latest version;
• bumps flutter_secure_storage to the beta version, so we can get rid of the workaround;
• re-enables the Kotlin compiler's validation of the JVM target version during Kotlin compilation against the target version set by the Java compiler. Previously, we were ignoring this compilation error. It might be better to enable it and explicitly override the JVM target setting for subprojects in build.gradle;
• removes tray_manager dependency.

BREAKING CHANGES: Please note that this change will set the minimum and target Java version to 23. As a result, developers will need to install JDK >= 23 to compile the project.

As the commit reveals, this PR primarily modifies dependencies related to the Android build process.

Therefore, I believe it's necessary to wait for a maintainer who focuses on Android to confirm it compiles on his side before merging.

Then I believe @kooWZ should be tagged for reviewing this. But I suppose he is struggling with OS(H) lately (so am I though). 😆
