feat(api): implement shipment commitment forms and document downloads

Introduce a complete workflow for managing shipment-related documents
and mandatory commitment forms between the Laravel backend and
WordPress frontend.

- Laravel:
  - Add `ShipmentCommitmentForm` model and migration to track signed
    forms per shipment.
  - Implement `CommitmentFormController` to handle fetching available
    forms and uploading signed documents.
  - Add PDF download endpoints for AWB, labels, and invoices via
    `ShipmentPdfController`.
  - Extend `User` model with notification management methods.
  - Add `FinanceOverviewWidget` for Filament dashboard.

- WordPress:
  - Implement AJAX handlers in `user-bridge.php` for PDF downloads and
    commitment form management.
  - Update `shortcodes.php` to display document download grid and
    dynamic commitment form upload interface in order details.
  - Add styling for document buttons and form status indicators in
    `ifnex-orders.css`.
