feat: sync ADCP schemas to latest, add brand compat and AAO member API (#132)

* feat: sync ADCP schemas to latest, add brand compat layer and AAO member API

- Update ADCP_VERSION from 3.0.0-beta.3 to latest; sync all 274 schemas
- Remove brand-manifest.json (dropped upstream); keep BrandManifest as
  backwards-compat stub in _generated.py for existing imports
- Add brand/brand_manifest cross-population on ResolvedBrand so both field
  names are always accessible regardless of which the registry returns
- Replace lookup_operator/lookup_operators with lookup_brand — operators are
  brands in the AAO registry, no separate endpoint needed
- Add Member type and list_members/get_member to RegistryClient for the AAO
  member directory (/api/members)
- Fix FieldModel.format_ → FieldModel.format (format is not a Python keyword)
- Fix CreateMediaBuyRequest test: brand_manifest field replaced by brand ref

* fix: resolve CI failures for BrandManifest and constr mypy errors

Two CI failures were found on PR #132:

1. Schema validation: NameError for BrandManifest in _generated.py
   - consolidate_exports.py hardcoded BrandManifest.model_rebuild() but
     BrandManifest is no longer defined (schema removed upstream in latest)
   - Fix: remove BrandManifest.model_rebuild() call; emit a backwards-compat
     stub class in the generated _generated.py output so existing imports work

2. Mypy valid-type errors in 5 generated files
   - datamodel-code-generator emits constr(pattern=...) as dict key types
   - mypy's Pydantic v2 plugin rejects this; requires Annotated[str, StringConstraints(...)]
   - Fix: add fix_constr_type_annotations() to post_generate_fixes.py to
     automatically rewrite the pattern after every schema sync

* fix: apply black formatting to _generated.py to match CI output

The local consolidate_exports.py run couldn't format with black
(not installed in system Python), leaving _generated.py with
single-line imports. CI has black installed, so it reformats to
multi-line, causing the validation check to always fail with a diff.

Pre-format the committed _generated.py with black so it matches
CI's regenerated output.

* fix: use uv run black in consolidate_exports.py for consistent formatting

When run outside the uv virtualenv, sys.executable may not have black
installed. This caused consolidate_exports.py to silently skip formatting,
producing single-line imports that CI's black would then reformat differently.

Try uv run black first (always available in this project), fall back to
sys.executable for environments without uv.

* fix: use pytest.mark.asyncio consistently in test_raises_on_invalid_limit

The test was using asyncio.run() directly in a sync method while all
surrounding tests use @pytest.mark.asyncio. Align for consistency.
