fix(test): resolve the remaining review findings on the control-plane auth test

Addresses the 5 lower-priority findings left as follow-up in the earlier
review, now that each has a concrete answer:

- Add gateway_name: str = GATEWAY_NAME to OrchestratorService.__init__
  (mirrors the existing orchestrator_name param) and thread it through
  _gateway(). Deletes the test's _IsolatedOrchestratorService subclass,
  which existed only to override a private method for this one kwarg —
  any caller needing gateway-name isolation can now use the public
  constructor. Backward compatible: every existing caller constructs
  OrchestratorService with keyword args and a sensible default is kept.

- Give the test its own fixed image tags (bot-bottle-orchestrator:itest,
  bot-bottle-gateway:itest) instead of the production :latest ones.
  _running_image_is_current() keys gateway staleness off the image tag's
  ID, not per-instance identity, so rebuilding the shared :latest tag from
  whatever's on disk during a test run could make a real host's running
  production gateway look stale and get force-recreated. Fixed tags (not
  per-run-suffixed, so they don't accumulate) fully decouple the two.

- setUp -> setUpClass/tearDownClass: all 5 tests are read-only checks
  against the same running control plane, so one shared container
  lifecycle replaces 5 (each of which paid its own container-start +
  image-build + health-poll cycle). Cuts the file's wall-clock roughly
  4x (11.5s -> 2.9-4.3s) and, combined with the network-rm cleanup from
  the previous commit, means one cleanup instead of five.

- Reuse OrchestratorClient (bot_bottle/orchestrator/client.py) instead of
  a hand-rolled urllib helper — the test now exercises the same
  request/response code path the real host CLI uses, rather than a
  private copy that could silently drift from it.

- Add the chown workaround test_multitenant_isolation.py already needed
  for this exact bind-mount: the orchestrator container has no USER
  directive, so it writes the registry DB as root into the throwaway
  host_root; chown it back before tempdir cleanup so that doesn't raise
  PermissionError on native Linux Docker (no UID remap, unlike Docker
  Desktop's macOS VM).

Verified: ran the suite twice in a row (idempotency — fixed image tags
don't accumulate, 5/5 pass both times, 2.99-4.33s each), the real
~/.bot-bottle/control-plane-token is untouched, zero leaked networks or
containers after either run, exactly 2 :itest images (not growing), the
full orchestrator unit suite (93 tests) and the sibling docker
gateway/broker integration tests still pass. pyright clean, pylint
10.00/10 on both changed files.
