refactor: 胶囊条改为纯进度展示，去掉"当前阶段"和"阶段耗时"

胶囊条 CapsuleStages 重构：
- 去掉 currentStage/progress 旧 props
- 每段只显示进度百分比 + 状态颜色（idle/active/done）
- 支持并行阶段（多个可同时 active）
- 数据由实际 PlanTask/DevTask/TestCase 状态驱动

进度数据来源：
- 调研：任务完成数 / 总数
- 产品/UI：需求完成数 / 关联数
- 开发：DevTask 进度（STATUS_PROGRESS 加权）
- 测试：已执行用例 / 总用例

版本列表页：
- 去掉"当前阶段"和"阶段进度"两列
- 替换为"状态"列（显示版本状态标签）
