frontend_build volume will shadow the built frontend assets.
The Caddy Dockerfile copies built assets to /srv/frontend in the image (line 9 of app/Dockerfile). However, mounting an empty frontend_build volume at /srv/frontend (line 62) will shadow those assets, resulting in an empty directory and broken frontend.
Either:
- Remove the
frontend_buildvolume from the caddy service (if only backend needs it) - Use a named volume with a separate build step that populates it
- Use a bind mount to a local directory containing the built assets

In `@docker-compose.yml` around lines 35 - 36, There is a circular depends_on
between the services named "backend" and "caddy" that will prevent Docker
Compose from starting them; break the cycle by removing one side of the
dependency (either delete the caddy -> backend depends_on entry or delete the
backend -> caddy depends_on entry) and, if sequential startup is required, rely
on a proper healthcheck-based depends_on condition (service_healthy) on only one
service; update both occurrences (the one shown and the similar entries around
lines 65-66) so only a single directed depends_on relationship remains.

Avoid a default Grafana admin password.
Line 130 falls back to admin, which is a weak default credential.

In `@docker-compose.yml` at line 130, Remove the insecure fallback default for
GF_SECURITY_ADMIN_PASSWORD in docker-compose.yml: do not use the ":-admin"
fallback for GRAFANA_ADMIN_PASSWORD; instead require the environment variable to
be set (or supply via Docker secret) so the container fails to start if no admin
password is provided, and update references to
GF_SECURITY_ADMIN_PASSWORD/GRAFANA_ADMIN_PASSWORD accordingly.
