Description

Fixes validation failures in CLI mode by ensuring the is_BBL_printer() flag is set before calling Print::validate().

Previously, the CLI slicing code called print->validate() before setting the is_BBL_printer() flag, causing validation to fail for cases where the validation logic depends on knowing whether it's a Bambu Lab printer.

The fix moves the BBL printer detection logic to occur before the validate() call, matching the behavior of BackgroundSlicingProcess::validate() used in the GUI path.

Screenshots

An example of the CLI and GUI slice result deviating. The 3mf being sliced is a completely standard project created in the OrcaSlicer GUI with the A1 Mini printer selected. This 3mf fails when sliced through the CLI while working as intended through the GUI.
