feat(admin): app_config 运营配置后台(rewards 等常量可后台配置)

- 新增 app_config 表 + model/repository/config_schema + admin config 路由与 schema + 测试
- rewards.py 及 ad_reward/signin/task/wallet/comparison_milestone repositories 接入可配置项;ad.py / admin/main.py 配套
- alembic merge(ebb6af5c0b56)合并本地 app_config(cfg1a2b3c4d5)与 incoming price_report/best_deeplink(b7e2c1a9f4d3)两 head
