Alexa 2e09042344 ci: run the agent with an init process; document the controller upgrade ...

- init: true on the agent so processes left behind by build tools are reaped,
  as the inbound-agent image asks for.
- Redeploying an older controller from docker-compose.yml upgrades Jenkins
  and moves it from Java 17 to 25: say to back up jenkins_home first, update
  plugins that fail to load, and run the job once before relying on it.
