feat: Add daily baseline payload logic (12:01 AM - 3:00 AM window)

- Replace saveRawPayload with saveDailyBaseline in all handlers - Full payloads only saved once per day per store during window - Inventory snapshots still saved every crawl (lightweight tracking) - Add last_baseline_at column to dispensaries table - Show baseline status in Per-Store Schedules dashboard - Display baseline window info (12:01 AM - 3:00 AM) in UI Reduces storage ~95% for high-frequency stores while maintaining full audit capability via daily baselines. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
