fix(intelligent-eval): task queue all-count + unresolved filter

任务队列全部任务计数把派生的 unresolved 字段也求和了（stats 含
pending/assigned/completed/failed/unresolved），导致显示 9 而实际 8 条。
- 全部任务 = 四态之和（排除 unresolved），与后端 stats 对齐
- 改为一次拉取全部 + 前端过滤（unresolved 是 pending+assigned 并集，
  后端 status 单选无法表达）；筛选/分页为前端状态，筛选变化重置到第 1 页
tsc 0 错误 vitest 16 passed
