评价本身也能填「观后感受」

- lib/db.php：reviews 表新增 feelings 列。建表语句里带上，同时补一条
  ALTER TABLE 迁移 —— 上一版已经上线过没有该列的 reviews 表，老库要能自动补列。
- lib/reviews.php：saveReview() 接收感受并落库；getMovieReviews()/getMyReview()
  把 feelings 解析成 key 列表（旧记录为 NULL → 空数组，不报错）。
- detail.php：评价表单加了「我看完的感受（可多选）」，与讨论用的是同一套感受；
  修改评价时原勾选自动回填，取消勾选即清空；已保存的感受在评价正文下方以只读标签展示。

感受仍然只存 key（happy/sad/…），emoji 与文案统一在 feelingCatalog() 里维护。
