feat(web): split plan page from tasks (FE-6)

- Nav overview group: 首页 / 任务 / 计划 / Agent 会话; tasks page drops the plan tab
- /console/tasks?tab=plan[&job=] redirects to /console/schedules[?job=]
- Plan page: 自动任务 compact grouped list (switch, interval preset/custom, last result,
  countdown, failure reason, run now/skip/run records) and Agent 巡检 cards (goal,
  allowlist, budget, upstream/model, trigger, cost per run, recent sessions); split stats
- Home plan band: two counts linking to #auto / #checks
- Docs: console-ia §7.4a, glossary, schedules runbook; smoke routes
