Fix CI JavaDoc job by installing linter-core from quick-build artifacts

The maven-full job downloads only target/ directories from maven-quick,
so linter-core is not available in the local Maven repository when
javadoc:javadoc runs for linter-cli. Install the pre-built JAR with
install:install-file before the matrix steps so inter-module
dependencies resolve without hitting Maven Central.

Also replace an unescaped '&' in FhirAuthorizationCache Javadoc to
silence invalid-input warnings during Javadoc generation.
