Api error response -> Schema.TaggedError (v3 vs v4, opaque types)

// example usage

export class ApiError extends Schema.TaggedError<ApiError>()("ApiError", {
    detail: Schema.String,
    instance: Schema.String,
    status: Schema.Number,
    title: Schema.String,
}) {
    static FromTagless = TaggedError.fromTagless<ApiError, "ApiError", typeof this.fields>()(this)
}

export const api = HttpApi.make("api").addError(ApiError.FromTagless)
