ci(docker): probe manifest before rewriting; defer docker_repo rewrite

Build 1417 of mina-mainline-branches-nightlies revealed the v1
rewrite's failure mode: when buildx asks the cache for a manifest and
gets 404, it errors out — there's no exec-fallback like the agent-side
docker-pull shim has. The 404 in 1417 came from zot's data disk being
100% full (414G/436G on the Hetzner Robot's RAID1), so its on-demand
sync from europe-west3 hit ENOSPC mid-blob-write; zot then tried gcr.io
(also 404, since euro-docker-repo paths are GAR-only), and returned
404 to buildx → build failure.

The infra side (disk-full) is being fixed via shorter gcDelay in the
gar-cache Ansible config. This change adds Mina-side resilience so
that whenever the cache can't serve a specific manifest — disk-full,
missing-upstream, zot bug, anything — the build falls back to the
upstream registry instead of erroring.

Changes:

* `gar_cache_has_manifest <full_ref>`: new helper. HEADs the manifest
  endpoint on the cache; a 200 means "cache will serve this manifest
  (already cached OR just on-demand-fetched)". Accept headers cover
  Docker v2 + OCI image + OCI image index media types.

* `rewrite_via_gar_cache` (image case): now requires a 200 from
  `gar_cache_has_manifest` before rewriting. Cache reachable but
  manifest missing → pass through unchanged.

* `rewrite_docker_repo_via_gar_cache <prefix> <image_name> <tag>`: new
  helper specific to Dockerfile-install-config's FROM. Constructs the
  full dep ref `${prefix}/${image_name}:${tag}` and probes it; only
  rewrites the prefix if the dep is currently servable.

* `build.sh`: docker_repo rewrite moves from line 163 to AFTER
  `export_docker_tag`. By then export_suffixes has populated
  BUILD_FLAGS_SUFFIX_ARG and CUSTOM_SUFFIX_ARG so we can reconstruct
  the exact FROM ref the Dockerfile will resolve. The rewrite block
  is gated on DOCKERFILE_PATH being Dockerfile-install-config; other
  services don't use docker_repo in FROM so... (continued)
