Add SSH hardening to user_data for future server rebuilds:
- PasswordAuthentication no (key-only access)
- X11Forwarding no (headless server)
- AllowTcpForwarding no (no SSH tunnels needed)
- AllowAgentForwarding no (no agent forwarding needed)
- MaxAuthTries 3 (reduced from 6)
- ClientAliveInterval 300 + ClientAliveCountMax 2 (clean up dead sessions)
Already applied manually to the existing server via
/etc/ssh/sshd_config.d/99-hardening.conf.

Add wildcard DNS record for *.internal.trails.cool (A + AAAA) so
internal services don't leak hostnames in individual DNS entries.
Move Grafana from grafana.trails.cool to grafana.internal.trails.cool.
Future internal services just need a Caddy block — no DNS changes.
