feat: Add Real-Time Inventory Tracking infrastructure

Implements per-store high-frequency crawl scheduling and inventory
snapshot tracking for sales velocity estimation (Hoodie Analytics parity).

Database migrations:
- 117: Per-store crawl_interval_minutes and next_crawl_at columns
- 118: inventory_snapshots table (30-day retention)
- 119: product_visibility_events table for OOS/brand alerts (90-day)

Backend changes:
- inventory-snapshots.ts: Shared utility normalizing Dutchie/Jane/Treez
- visibility-events.ts: Detects OOS, price changes, brand drops
- task-scheduler.ts: checkHighFrequencyStores() runs every 60s
- Handler updates: 2-line additions to save snapshots/events

API endpoints:
- GET /api/tasks/schedules/high-frequency
- PUT /api/tasks/schedules/high-frequency/:id
- DELETE /api/tasks/schedules/high-frequency/:id

Frontend:
- TasksDashboard: Per-Store Schedules section with stats

Features:
- Per-store intervals (15/30/60 min configurable)
- Jitter (0-20%) to avoid detection patterns
- Cross-platform support (Dutchie, Jane, Treez)
- No crawler core changes - scheduling/post-crawl only
