test: 提升ActivityController测试覆盖率 - 新增topN边界测试

Browse Source 
- 新增3个测试覆盖topN参数的边界条件
  * topN超过列表大小的场景
  * topN为0的场景
  * topN为负数的场景

覆盖率提升：
- 总体分支覆盖率: 63.3% → 63.6% (+2个分支)
- Controller包: 84% → 89% (+5%)
- ActivityController: 77% → 更高
- 新增测试用例: 3个
- 距离70%目标: 还需40个分支

本次会话总成果：
- 新增测试: 12个
- 分支覆盖: +7个 (404→411)
- Controller包: 73% → 89% (+16%)
