50-state trucking compliance: services, checker, order page, CA landing

- Migration 079: state_trucking_requirements table seeded for all 51 jurisdictions
  (IRP, IFTA, weight-distance taxes, MCP/CARB, intrastate authority, state DOT)
- Migration 080: carrier_operating_states tracking table
- 13 new state trucking services in catalog ($99-$599)
- StateTruckingHandler with state-specific admin todos
- DOT compliance checker: 7 new state-level checks (IRP, IFTA, weight tax,
  MCP/CARB, emissions, intrastate authority, state DOT number)
- New API endpoint: GET /api/v1/dot/state-requirements
- DOT order page: state compliance service cards with auto-preselect
- California trucking landing page (MCP + CARB + IRP + IFTA)
- Fix: DOT checker nav missing Trucking/DOT section
- Fix: All 8 DOT intake pages missing style block (dangling text)
- Fix: DOT confirmation email now says "Order Confirmed" not "Action Required"
- Fix: MCS150/BOC3/StateTrucking handlers missing async process() method
- Fix: StateTruckingHandler connection leak + slug resolution
