Adds (AMS) filament sync options: Only sync color / sync all (#12169)

This PR adds a new filament sync mode setting for device-based filament synchronization.
Users can now choose between syncing both filament preset + color (current behavior) or syncing color only, so calibrated local filament profiles are preserved while still updating slot colors from the printer.
It also includes small UI improvements for the new preference entry and sync status messaging.
