fix: change serde field naming from camelCase to snake_case with explicit renames

Remove container-level camelCase rename attributes from LoginRequest, LoginResponse, EnrollRequest, EnrollResponse, PeerView, and GatewayView structs. Add explicit field-level serde rename attributes for snake_case fields (access_token, refresh_token, os_version, app_version, device_fingerprint, public_key, assigned_ip, profile_revision) to match backend API contract.
