Clean up declared dependencies #13749

mvn dependency:analyze across the Maven repositories reports dependencies that are declared but unused, declared in the wrong scope or in a parent that does not need them, and third-party libraries the code uses but only gets transitively. Every finding below was checked against the sources, applied in a separate pull request per repository, and kept only if the full test suite still passed; the analysis then no longer reports it.

Not changed on purpose: used-but-undeclared Maven API, Sisu/Guice/javax.inject, test-framework and SLF4J artifacts (declaring Maven core artifacts follows separately), and anything that only a build with GraalVM, or an external tool, could verify.
