chore!: remove all deprecated routes (including /openai/v1/ ones) (#4054)

This PR removes all routes which we had marked deprecated for the 0.3.0
release.

This includes:
- all the `/v1/openai/v1/` routes (the corresponding /v1 routes still
exist of course)
- the /agents API (which is superseded completely by Responses +
Conversations)
- several alpha routes which had a "v1" route to aide transitioning to
"v1alpha"

This is the corresponding client-python change:
llamastack/llama-stack-client-python#294
