[feat] Migrate to Jobs API (PR 2 of 3)

This PR switches the frontend from legacy /history and /queue endpoints
to the unified /jobs API.

Key changes:
- Rewrite TaskItemImpl in queueStore.ts to wrap JobListItem
- Update api.ts getQueue()/getHistory() to use Jobs API
- Update all queue composables (useJobList, useJobMenu, useResultGallery)
- Update useJobErrorReporting to use execution_error.exception_message
- Update JobGroupsList.vue workflowId access
- Update reconciliation.ts to work with JobListItem
- Update all related tests

Breaking changes:
- getQueue() now returns JobListItem[] instead of legacy tuple format
- getHistory() now returns JobListItem[] instead of HistoryTaskItem[]
- TaskItemImpl.outputs now lazily loads via loadFullOutputs()

Part of Jobs API migration. Depends on PR 1 (jobs-api-pr1-infrastructure).
