feat(fields): 可选字段(非 required)编辑态可清空,统一 :clearable=!required

之前 Select/Relation 编辑态根本没 clearable(可选也删不掉),String/Textarea/Date 又恒清。
现统一 String/Textarea/Select/Relation/Date 的 edit 控件 clearable=!required:可选给清空、必填不给。
Relation 清空归一成 null(el-select 单选清空发 '',ObjectId 存 '' 会 cast 报错)。
已知例外:Number 用 el-input-number 无 clearable 属性,只能手动清空输入框、无按钮。
