feat: 增强代理结算和账单管理功能

- 在多个控制器中引入 SettlementPartyEnrichment 服务，以优化代理结算和账单的处理逻辑。
- 更新 AgentSettlementBillIndexController 和 AgentSettlementBillShowController，支持根据账单 ID 和关键字进行查询。
- 在 AgentSettlementPeriodCloseController 中添加对站点管理权限的验证，确保只有具备相应权限的管理员能够关闭账期。
- 在 AgentSettlementPeriodIndexController 中更新账期数据的返回格式，提升数据的完整性和可用性。
- 引入对相对占成比例的支持，增强代理资料的管理能力，确保数据一致性。
