fix(docker): gate gh/az seeding on its switch; no shared git sign-in for non-admin clones

Addresses the review on #472.

- CRED_STORES: `.config/gh` and `.azure` now carry `enabledByEnv`
  (CODEMAN_AGENT_IMAGE_INSTALL_GH / _AZ), and resolveDockerCredentialArtifacts
  skips a store unless that variable is exactly `1`, read at container
  create. A host that merely has ~/.config/gh/hosts.yml or a plaintext MSAL
  cache no longer copies them into every case container. Tests: the default
  environment seeds neither even with the files present, and each store
  follows only its own switch.
- Multi-user mode: a non-admin's Clone Repo clone and preflight run with
  `git -c credential.helper=` (GIT_NO_CREDENTIAL_HELPERS, placed before the
  subcommand), so the server account's helpers are never lent to them.
  Verified against a real private repo that it also clears the URL-scoped
  credential.<url>.helper entries, and that public clones still work.
  Tests: the argv in test/git-clone.test.ts, and the route decision
  (non-admin cleared; admin and single-user kept) in
  test/routes/case-clone-credential-helpers.test.ts.
- Docs: recreate the case container to pick up seeds (docker/README.md,
  Docker-Cases wiki, docker-cases.md); the multi-user behaviour in
  docker/README.md and security-architecture.md; "functionally unchanged"
  instead of "unchanged" for an image built with both switches off
  (server.Dockerfile comment, README, changeset).
