Route Tomcat archive through MASS

[bric3]

What Does This Do

When MASS_READ_URL is present, the Spring Boot Tomcat nested application resolves the Tomcat ZIP through MASS at /internal/artifact/dlcdn.apache.org. Without that environment variable, local builds keep using https://dlcdn.apache.org.

Motivation

CI should send build-time archive downloads through MASS when the upstream host is already allowed. The Tomcat archive host is covered by the existing .apache.org:443 suffix entry.
