feat(scheduler): recorder scheduling — UI, CRUD, tick loop, recurrence
- New Ingest → Schedule page: upcoming/past/all tabs, status badges
(pending / recording / completed / cancelled / failed), 10s
auto-refresh, cancel/delete actions
- New Schedule modal: name, recorder dropdown, datetime-local start/end,
recurrence (one-shot / daily / weekly), sensible defaults (+5min / +35min)
- Backend: migration 009 (recorder_schedules), routes/schedules.js
(list/create/edit/cancel/delete), scheduler.js tick loop polling every
15s; transitions trigger /recorders/:id/start and /stop via in-process
HTTP so we reuse the full container orchestration path
- Recurring schedules: tick loop auto-queues the next occurrence on
completion (daily = +24h, weekly = +7d)
- Sidebar + app.jsx route wired in, schedule-row table style added
