Tighten request and provider typing across the SSE pipeline to fix
nullability and inference issues in Claude compatibility, wildcard
routing, usage tracking, proxy fetch, and response sanitization.
Address runtime edge cases by normalizing Bailian hosts, guarding TLS
session creation, preserving custom provider base URLs, and using safer
OAuth form param construction during token refresh flows.
Update dashboard data path exports and usage stats typing, and align
E2E/unit tests with paginated API responses, internal model sync auth,
and current response payload shapes.
