Why can’t the project be deleted?

The project can’t be deleted if it’s linked to a contract (regardless of the contract’s status — Draft, Active, or any other status), and the message “You can’t delete a project with linked contract!” appears.

As for cost sheets, quotations, and stock requests linked to the project, these don’t block deletion — they’re automatically deleted along with the project itself once the deletion is confirmed, with a warning message appearing to clarify this before the final confirmation.
