fix(vector_stores): restrict vector store and index deletion to proxy admins only

Non-admin keys could delete vector stores via DELETE /v1/vector_stores/{id}
and delete Azure AI Search indexes via the azure_ai pass-through endpoint.
Added PROXY_ADMIN checks to both paths (registered-index and generic fallthrough).
