Bug: The feature flag organizations:workflow-engine-orgincidentindex-get is used without being registered, causing features.has() to always return False and making the flag non-functional.
_{Severity: MEDIUM}

Suggested Fix

Register the feature flag organizations:workflow-engine-orgincidentindex-get in the feature flag definitions, likely in src/sentry/features/temporary.py, to match the pattern used by other similar workflow engine flags.

Potential issue: The feature flag `organizations:workflow-engine-orgincidentindex-get`
is used in the code but has not been registered. The `features.has()` method is designed
to handle unregistered flags by catching a `FeatureNotRegistered` exception and silently
returning `False`. Consequently, the check for this flag will always fail, and the new
per-endpoint flag will be non-functional. This prevents the intended independent rollout
of the workflow engine for this specific endpoint, as the code path can never be
activated via this new flag.
