Fix build for environments without sandec.jfrog.io access

- Replace jpro-gradle-plugin with standard application plugin
- Add custom jproRelease task to create distributable ZIP
- Fix Java compatibility from 22 to 21 (matching available JDK)
- Fix single-quote dependency string that prevented $jproVersion interpolation
- Remove sandec.jfrog.io buildscript repository from settings.gradle

Note: Build still requires JavaFX Gradle plugin from plugins-artifacts.gradle.org
which may also need network access. Further work needed to fully resolve.
