fix(billing): 删任务/删项目级联吞 ACTIVE 预留致 reserved_balance 永久冻结(审计 I2)

- 根因: CreditReservation.task 是 OneToOneField(CASCADE), AITask.project 也是 CASCADE
  —— 删项目→级联删任务→ACTIVE 预留行被吞, 账户冻结份额永不归还(实测 4 账户漂移共 ¥42,
  且随删项目持续增长)
- 修法: billing/signals.py 挂 AITask pre_delete, 删除前先 release_credit 释放(级联同样
  触发, release 自带行锁+幂等); apps.py ready() 接线
- 回归测试 x3: 直删任务/删项目级联/已扣费不重复释放
- qa/repair_reserved_drift.py: 存量漂移回填脚本(dry-run 默认, --apply 落 RELEASE 流水),
  已对线上 4 账户执行并复验清零
- qa/function-audit/output: 本轮 18 页模拟点击审计报告(0 真死按钮 0 JS 报错)

验证: 后端测试 213/213 通过, django check 无警告
补齐 aab4d7e: 该提交带走了 signals.py 之外的测试轮改动, 信号挂载点与回归测试在本提交收口
