* fix(auth): add workaround for Docker client auth with mixed anonymous policies

Docker client fails to authenticate to protected repositories when basic auth
(htpasswd/LDAP) is used with mixed access policies (some repos anonymous,
some requiring auth). This happens because Docker determines whether to send
credentials based on the /v2/ response - if it returns 200, Docker assumes
no auth is needed anywhere.

Add `forceDockerClientAuth` config option that, when enabled, forces 401 on
/v2/ for Docker clients, triggering Docker's authentication flow.

This workaround only affects Docker clients (detected via User-Agent).
Podman and other OCI-compliant clients are unaffected.
