/**
 * Tests for isBambuLabSpool helper.
 *
 * The function is permissive: any non-empty non-zero value of tray_uuid OR
 * tag_uid returns true. It does NOT validate hex-length or character set —
 * its job is solely to suppress assign/unassign actions on RFID-managed slots
 * whose state is owned by the printer firmware.
