test(codex): sync chat preset snapshot after native Responses migration

Commit 273cc48c migrated 7 CN providers from openai_chat to native
openai_responses and refreshed model ids on the remaining chat-only
providers, but the codexChatProviderPresets snapshot was not updated,
breaking the unit tests on main.

Drop the migrated providers (DouBaoSeed, Bailian, Longcat, MiniMax,
MiniMax en, Xiaomi MiMo x2) from the chat list, sync GLM/StepFun/Ling
model ids, and add a test locking the migrated presets to
openai_responses with no modelCatalog (so the local route-mapping
toggle stays unchecked).
