feat: 增强代理和玩家管理功能

- 在多个控制器中更新权限检查逻辑，确保管理员能够更灵活地管理代理和玩家。
- 在 AdminPlayerStoreController 中引入对玩家创建能力的验证，确保只有具备相应权限的管理员能够创建玩家。
- 更新请求验证逻辑，新增 credit_limit、rebate_rate 和 extra_rebate_rate 字段，以支持更细粒度的玩家管理。
- 在 AgentNodeProfileController 中添加对父代理能力授予的验证，确保子代理的权限在父代理范围内。
- 引入 AgentProfileFieldRules 以简化代理资料更新请求的规则定义，提升代码复用性。
