trucking wrap-up: close-out becomes a paid order + workflow

- Checker closing mode now pitches a done-for-you 'Trucking Wrap-Up' ($199)
  with a buy button to /order/dot-compliance?services=carrier-closeout, instead
  of a lead form. DIY checklist replaced by what's-included list.
- Entity dissolution offered as a paid add-on with the lawsuits/liens/judgments
  warning before dissolving.
- New catalog services: carrier-closeout ($199), entity-dissolution ($199).
- CarrierCloseoutHandler orchestrates the sequential shutdown workflow
  (final MCS-150 out-of-business, MC revoke, UCR cancel, IFTA/IRP + state
  closures; dissolution branch for the add-on) as admin-tracked tasks.
- Sell-your-trucks: single shared form with quick-cash / marketplace / both;
  name field is now a real first+last name (no corp-name prefill).
- tickets categories: add truck_sale_both, drop business_closeout (now an order).
