task(f4b5cc37-e27d-480a-ac94-f78a8b24a4d1): Implement M1 account and session module with e2e tests

- Add AuthApi with 5 endpoints (LoginByAccount, LoginByMobile, etc.)
- Implement dual-layer envelope unwrapping in ApiCaller for HTTP 500 + ASP.NET exceptions
- Add DynamicBaseUrlInterceptor for runtime server switching
- Implement SessionRepository with login state management and token persistence
- Add Mine/Login/Config/ChangePassword UI with ViewBinding and state machines
- Replace placeholder MineFragment with business implementation
- Hide bottom navigation when sub-pages are on back stack
- Add 33 new strings and login_error color resource
- Provide AuthApi in NetworkModule DI
- Verified: 5/5 e2e negative tests passed, dual unwrapping works on real responses
