feat(ui): order totals, decimals, mobile modal cards, set editing

- Dashboard/Logs: Total column with 2 decimals (order_total)
- Order detail modal: totals summary row (items total + order total)
- Order detail modal mobile: compact article cards (d-md-none)
- Mappings: openEditModal loads all CODMATs for SKU, saveMapping
  replaces entire set via delete-all + batch POST
- Add project-specific team agents: ui-templates, ui-js, ui-verify,
  backend-api
- CLAUDE.md: mandatory preview approval before implementation,
  fix-loop after verification, server must start via start.sh
