fix(hermesagent): move service details from CT footer to MOTD

Trims the verbose 12-line CT footer to the standard pattern plus
essential first-run setup steps. API server, API key, and dashboard
SSH tunnel details are now displayed on every SSH login via
/etc/profile.d/hermes-hint.sh instead.

Addresses PR feedback from CrazyWolf13.
