Switch from a custom caddy-dns/gandi image built on-host to the official
caddy:2 image with per-host ACME HTTP-01 certificates. Removes the
Dockerfile, env.j2 (Gandi token), on-host image build/ship/load tasks,
the caddy-image Makefile target, and the wildcard DNS-01 Caddyfile.
Each route now gets its own server block and automatic certificate.

Implements the Caddy reverse proxy role (ADR-024): builds boma/caddy-gandi:latest
on-host (caddy-dns/gandi plugin), renders Caddyfile from route catalog, brings
Compose project up. Adds community.docker to requirements.yml, production group_vars,
and a caddy-image Makefile target.
