新增: 父⑤⑤.2收尾(评分拆const+表单补全+css陷阱) + priority跨层映射修复

父⑤⑤.2(DEC-03 c / DEC-04 a):
- #6 scoring.rs 关键词拆 const(FEASIBILITY_POS/NEG + IMPACT + URGENCY 4 组,零行为变化,df-ideas 22 测试过)
- #9/#10 Ideas.vue 表单补 tags(逗号分隔对标 KnowledgeDetail)+priority 下拉+source,i18n 中英对称
- css 陷阱修:components.css .modal-* 通配→"modal 系列"(避 */ 闭合,memory css-comment-star-slash-trap)

priority 跨层映射修复(verify agent 发现的预存 bug):
- idea.rs priority_from_i32 原跟 df-types 枚举(0=Low),与前端约定(0=critical,api/types.ts:141+Tasks.vue)反
- 改手动映射对齐前端(0=Critical/1=High/2=Medium/3=Low),Priority as_str 序列化不受影响
- 校验注释同步更正(我父①①.3 加的 Low=0 注释)

父⑤ 全闭环(⑤.1/①.4/⑤.2)。css warning 清零。
