Deploy wiring for the observability stack (the services and collector
config landed in the previous commit):
- Caddyfile.dev: route /grafana/* to galaxy-grafana:3000 (Caddy
sub-path mode, Grafana keeps its own login) and /mailpit/* to
galaxy-mailpit:8025 behind dev basic-auth, so the captured-mail UI
(every message, relayed or not) and Grafana are reachable through the
single dev origin.
- dev-deploy.yaml: seed the monitoring config tree to a stable,
reboot-surviving host path (GALAXY_DEV_MONITORING_DIR) before bringing
the stack up, and inject the Grafana admin password from a Gitea
secret (GALAXY_DEV_GRAFANA_ADMIN_PASSWORD; empty falls back to the
compose default).
