feat(KB-088): clear failed status when moving tasks and improve error display

- Fix moveTask to clear status/error/worktree/blockedBy when moving from in-progress to todo/triage
- Add error message display in TaskCard for failed tasks with truncation
- Add prominent error alert in TaskDetailModal for failed tasks
- Refactor usage tracking: move from app/components to dashboard/src/
- Add usage.ts and usage.test.ts for centralized usage tracking
- Remove UsageIndicator and useUsageData from app/ directory
- Update styles.css for error display components
- Update executor tests for error handling
- Add changeset for patch release
