feat: repair-POS integration, receipt formats, manager overrides, price adjustments

- Add thermal/full-page receipt format toggle (per-device, localStorage)
- Full-page receipt uses clean invoice layout matching repair PDF style
- Settings page reorganized into tabbed sections (Store, Locations, Modules, Receipt, POS Security, Advanced)
- Manager override system: configurable PIN prompt for void, refund, discount, cash in/out
- Discount threshold setting: require manager approval above X%
- Consumable product type: tracked for internal job costing, excluded from POS search, receipts, and customer-facing totals
- Repair line item dialog: product picker dropdown for parts/consumables from inventory
- Repair → POS checkout: load ready-for-pickup tickets into repair_payment transactions with proper tax categories (labor=service, parts=goods)
- Transaction completion auto-updates repair ticket status to picked_up
- POS Repairs dialog with Pickup and New Intake tabs, customer account lookup
- Inline price adjustment on cart items: % off, $ off, or set price with live preview
- Order-level discount button with same three input modes
- Backend: migration 0043 (consumable enum + is_consumable flag), createFromRepairTicket service, ready-for-pickup endpoint
- Fix: backend dev script uses --env-file for turbo compatibility
