docs: add post-install keytool import for the JDK cacerts trust store

Document how to make the installed JDK trust an internal CA at application
runtime by importing it into $JAVA_HOME/lib/security/cacerts with keytool
after setup-java runs. Clarifies this is the runtime trust layer, distinct
from the download/transport layer (NODE_EXTRA_CA_CERTS), and notes hosted vs
self-hosted persistence caveats.
