v3: PostgreSQL backend — 20K rows seeded, server-side SQL filtering

Browse Source 
- Added PostgreSQL 16 Alpine service to Docker Swarm stack
- db.py: schema for 17 tables, auto-seed from jv_data.json on first boot
- /api/dashboard/data?start=&end= — server-side SQL filtering
  All Time: 0.43s (was 4MB JSON download stuck loading)
  Filtered (12mo): 0.20s with ~90% less data transferred
- Dashboard HTML patched: calls API instead of static JSON
- Integer casting for IsNewCustomer/HasDiscount/IsFreeShipping
- Advisory lock prevents race condition during parallel worker startup
- Returning Revenue now shows correctly: £14.5M (75% of total)
