feat: 06 互动与内容治理落地（评论 / 点赞 / 举报 / 敏感词 / 审核留证）

为什么：
1) 产品侧要先把内容治理闭环跑通才能谈上线：评论可发布、可翻页、可删除，
   违规内容能在后台被审核与驳回，举报要有工单可追溯。本提交把这套补齐。
2) 审核不能只靠人肉：敏感词按 BLOCK/REPLACE/REVIEW 三档处置，
   机审通过即发布（可配置为 PRE_REVIEW 全部先审后发），人审与机审的结论
   都写进 content_audit_record，争议时可回答"当时凭什么放行/驳回"。
3) 举报处理必须与处置打通：结论成立会联动驳回被举报评论，并可选同时封禁被举报用户，
   避免"工单处理完了但违规内容还挂着"。
4) 顺带修复一个真实缺陷：user_favorite / content_like 上有唯一索引，而全局配置会把
   deleteById 改写成逻辑删除，导致取消收藏/点赞后旧的 deleted 行仍占位，
   再次收藏或点赞直接撞唯一索引报错。关系类数据没有留证价值，改为显式物理删除，
   并补了"取消后再来一次"的回归自测。
