Replace deprecated java.net.URL constructors with URI-based alternatives for Java 20+ compatibility

The java.net.URL constructors have been deprecated
since Java 20 and are marked for removal in a future JDK release.
This patch replaces all usages of deprecated URL constructors across the
codebase with the recommended URI-based alternatives.
