/**
 * log10x_update_settings — update user-account metadata via
 * `POST /api/v1/user`. Idempotent. Use case: change analyzer cost
 * ($/GB), display name, etc., without leaving chat to visit
 * console.log10x.com.
 *
 * Backend handler: backend/lambdas/user-service-go/cmd/user/main.go
 * (handleUpdateProfile). Documented at mksite/docs/api/manage.md
 * "Update User" section.
