Add wipe_tower_type printer setting to replace vendor-based wipe tower selection

Previously, wipe tower behavior was determined by checking if the printer
  was a QIDI vendor. This introduces a configurable enum (Type 1 / Type 2)
  so any printer can select its wipe tower implementation. BBL printers
  remain hardcoded to Type 1. Qidi profiles default to Type 1.
