feat(freight): add company logo setting applied to every generated document

New logo-settings module (mirrors stamp-settings): single uploaded logo,
stored via FilesService/MinIO, injected as a data URL into invoice/receipt,
contract, warehouse, train-scheduling, and payment-receipt PDFs. Adds a
matching backoffice settings page and settings:logo:view/manage permissions.
