refactor(integrations): 穿山甲验签改 GroMore SHA256 + pangle/wxpay 从 core 移入 integrations

- 验签: pangle.build_sign/verify_callback_sign 改为 GroMore 官方
  sign=SHA256("{m-key}:{trans_id}")(普通 SHA256,只签 trans_id);
  回调响应改成 GroMore 要求的 {is_verify, reason}
- 发奖: 按回调 reward_amount 发金币(rewards 带回退/夹紧),ad_reward 幂等 + 每日上限
- 分层: app/core/{pangle,wxpay}.py → app/integrations/(对齐 jiguang/meituan/sms);
  更新 ad.py / crud/wallet.py / scripts/sim_pangle_callback.py / 测试的 import
  (含 test_withdraw 的 monkeypatch 路径 app.core.wxpay→app.integrations.wxpay)
- 测试: test_ad_reward + test_withdraw 共 17 项通过
