Use archive instead of permanent delete for orders (keep record, exclude from stats)

Users have asked for an "archive" option instead of permanent delete for orders. They want to keep a record of archived orders so they can look back if something goes wrong, report on cancellations, and prevent staff from skirting the system by deleting. The action would be permission-based (like the current delete permission) and would exclude the order from stats—similar to how archived or rejected quotes are handled—but the record would remain visible or recoverable rather than being removed entirely.

Why it matters: Client care and managers want auditability and the ability to track who archived what; permanent delete makes people nervous and removes the ability to investigate or correct mistakes.
