fix(ai): address PR code-yeongyu#193 review — re-port OAuth, protocol P1s, drop GLM ZCode

Re-port OAuth flows from utils/oauth to auth/oauth with bundledLoaders,
route Cursor through Connect/protobuf ChatService, fix GitLab PAT exchange
and gpt-5.1 chat-completions routing, delist Perplexity session OAuth from
/login, exclude Google CCA providers from API-key login, remove unofficial
GLM ZCode login, keep browser smoke Node-free, and update stale kimi-coding
live-test model ids.
