Remove GET /api/v4/chaos/test endpoint and chaos tag
BreakingBreaking change
This is a breaking change — integrations that rely on the affected behaviour will need updates before the change rolls out.
What changed
The GET /api/v4/chaos/test endpoint and its associated chaos tag have been removed from the OpenAPI spec. Any client or integration that calls this endpoint will receive a 404 or equivalent error. The endpoint was an internal feature-flag observability tool (with intentional chaos behaviour), so real-world external consumers are unlikely, but its removal is technically a breaking change.
