fix(ci): image variation openai sdk 2.24.0 compat + swap bedrock nova-premier to nova-pro (#23066)

* fix(ci): fix image variation test for openai sdk 2.24.0 and swap nova-premier to nova-pro

image_gen_tests: openai==2.24.0 (bumped Feb 25) requires BytesIO objects to have
a .name attribute for MIME type detection in multipart uploads. Add .name to the
fixture so create_variation works. Also guard with OPENAI_API_KEY skipif.

proxy_e2e_anthropic_messages_tests: nova-premier requires provisioned throughput
not available via standard on-demand cross-region inference on the CI account.
Swap to nova-pro which uses standard inference profiles.

* fix: remove skipif, keep only .name fix for openai sdk compat
