Fix backend/Dockerfile to COPY templates/ and static/ (the go:embed
assets from Tasks 5-7) alongside *.go, plus backend/.dockerignore which
was silently excluding both directories from the build context — the
Dockerfile fix alone still failed the build. Wire WEB_PASSWORD through
docker-compose.yml, add a second Traefik router (mangaweb) plus explicit
service labels on both routers in docker-compose.prod.yml, and document
the new variables and deploy steps in .env.example, DEPLOY.md, and
CLAUDE.md.
Add traefik.enable + Host/entrypoints/tls/certresolver/service labels to the
prod override, driven by MANGA_API_HOST / PROXY_NETWORK / TRAEFIK_ENTRYPOINT /
TRAEFIK_CERTRESOLVER env vars (documented in .env.example).
