Teach the pin inventory the conditional openai-client shape

The SSRF pin inventory asserted a literal unconditional pin in the
openai-client; the previous commit made that pin conditional for the
two person-typed base-URL tags. The guard now asserts the exact
ternary — allowlist helper for gateway/admin-key, literal true as the
floor — so neither the floor nor the condition can drift silently.
