Restore the Maven dependency cache for saving runs that never save it.

The restore step runs only when save != 'true'. The save step runs only when save == 'true' and the cache type is application-server-reactor. A default-branch push, schedule, or dispatch run with cache type application-server-tests therefore matches neither step and resolves the whole dependency tree from the network. server-api and server-database in .github/workflows/ci-build.yml use that cache type.

-      if: steps.identity.outputs.save != 'true'
+      if: steps.identity.outputs.save != 'true' || inputs.cache-type != 'application-server-reactor'

In @.github/actions/setup-caches/action.yml at line 57, Update the cache restore
condition in the setup-caches action so application-server-tests runs that do
not save a cache still restore the Maven dependency cache; preserve the existing
save condition for application-server-reactor and ensure the restore/save
conditions cover all supported cache types without overlap.
