feat: 5-tier pricing, market ticker integration, and delivery stats

Major update spanning pricing, market data, and analytics:

- Pricing: Replace single-price service fees with 5-tier pricing for
  same-day, prime, and emergency deliveries across create/edit/finalize
- Market: Add Ticker_Price and CompanyPrice models with endpoints for
  live commodity prices (HO, CL, RB) and competitor price tracking
- Stats: Add daily/weekly/monthly gallons endpoints with multi-year
  comparison and YoY totals for the stats dashboard
- Delivery: Add map and history endpoints, fix finalize null-driver crash
- Schema: Change fill_location from INTEGER to VARCHAR(250), add
  pre_load normalization for customer updates, fix admin auth check
