重构: P0-4 IdeaRecord.status union类型化(试点·类型安全)

- types.ts: 新增 IdeaStatus union(draft|pending_review|approved|rejected|promoted|archived, 对齐后端df-types IdeaStatus serde snake_case) + IdeaRecord.status string→IdeaStatus
- Ideas.vue/IdeaDetail.vue/IdeasPanel.vue: statusOptions/statusLabelKey/onStatusChange/emit收窄 类型IdeaStatus(编译期校验拼写错)
- stores/project.ts/state.ts: 比较 IdeaStatus
后端契约: union 6值=df-types IdeaStatus serde, IPC/DB不变零行为变更
P0-4试点跑通: 推广路径验证(union+父子类型传递+emit收窄); 剩余TaskRecord/AiToolCallInfo/WorkflowRecord/ProjectRecord status待推广
