fix(providers): bind saved Requesty credentials to a canonical saved URL

The Requesty retarget boundary only checked the launch URL. A profile
saved for a non-canonical Requesty-route URL and relaunched with a shell
OPENAI_BASE_URL on canonical Requesty was not treated as a retarget, so
its proxy key, REQUESTY_API_KEY, custom-auth trio and custom headers all
reached Requesty.

Profile apply already treats only a canonically saved Requesty profile's
key as a Requesty key. Use the same rule on relaunch: saved credentials
follow only between canonical Requesty URLs. Any other launch drops them,
including the dedicated-key fallback. Explicit shell credentials still
apply.
