The Configure AMS Slot picker was hardwired to 0.4mm (nozzleDiameter
prop never passed from PrintersPage / SpoolBuddyAmsPage), so a 0.6
machine could only set 0.4 profiles on its trays. Resolve the real
installed nozzle per-AMS (ams_extruder_map on dual-nozzle) and pass it
in. Separately, nothing validated the sliced nozzle against the
installed one, so a mismatch reached the printer as a cryptic HMS
_8012 "Failed to get AMS mapping table". Add a fail-safe pre-dispatch
guard in _start_print that fails the item with an actionable message
before upload; no slice diameter or no reported nozzles = no-op.
