Stop hardcoding a generic watch_services list on every agent install

The installer wrote the same service list (ollama, homeassistant, mysql,
mariadb, nginx, apache2, docker) onto every host regardless of what it
actually runs, causing false "Service Down" alerts on hosts that never
installed those services. Default is now empty; watch_services should be
set per-host to match what's actually running there.
