Match the existing api-group convention: one module per resource family
with multiple Resource classes per file (cf service_api/dataset/dataset.py
with 7 routes, console/auth/oauth_device.py with 2 before this branch).
The Phase B-D fragmentation (one file per route under
controllers/openapi/oauth_device/) was inconsistent with the codebase.
Collapse into:
controllers/openapi/oauth_device.py (5 routes: code, token,
lookup, approve, deny —
account branch)
controllers/openapi/oauth_device_sso.py (4 routes: sso-initiate,
sso-complete,
approval-context,
approve-external —
EE-only SSO branch)
The split mirrors the original pre-migration layout: account branch in
console/auth/oauth_device.py, SSO branch in controllers/oauth_device_sso.py
(root). Both legacy mount files updated to import from the new modules.
No behavior change; 59 tests still green. Test files updated to import
from the consolidated module paths.

Canonical class OAuthDeviceCodeApi now lives in
controllers/openapi/oauth_device/code.py and is registered on
openapi_ns at /openapi/v1/oauth/device/code. service_api/oauth.py
re-registers the same class object on service_api_ns at
/v1/oauth/device/code so existing callers keep working until Phase F.
KNOWN_CLIENT_IDS literal moves to dify_config.OPENAPI_KNOWN_CLIENT_IDS
(CSV-parsed, default "difyctl") so new CLIs / SDKs can be admitted
without code changes (CLAUDE.md rule 8 — no magic strings).
_verification_uri helper moves with the handler. Single source of
truth — no duplicated logic between the two mounts.
