maziggy a2c9eef87c fix(safety): invert bed-jog Z direction on A1 / A1 Mini bed-slingers (#1334) ...

On A1 / A1 Mini, clicking the "Up" arrow on the printer-card bed-jog
  control sent the nozzle straight into the build plate. Reporter
  triggered it with the 50 mm step and crashed their nozzle.

  Root cause: the bed-jog UI was designed against the X1 / P1 / H2 family
  where the bed is the Z-axis and Bambu's firmware homes Z=0 at the top,
  so G1 Z- raises the bed toward the toolhead (decreases the nozzle-bed
  gap). The frontend maps "Up" to negative distance with that convention
  in mind.

  A1 / A1 Mini are bed-slingers: bed moves on Y, toolhead moves on X+Z,
  firmware uses standard cartesian Z (Z+ = toolhead up). On those models
  G1 Z-10 drives the toolhead DOWN 10 mm. There was no model
  classification at the bed-jog code path, so every printer got the same
  X1-convention G-code.

  Fix: new is_bed_slinger(model) helper in printer_manager (sibling to
  existing supports_chamber_temp / has_stg_cur_idle_bug, reuses the
  already-defined A1_MODELS frozenset which covers display names and
  internal codes N1 / N2S). The bed-jog route now inverts the signed
  distance before emitting G-code when the printer model is in that set,
  so UI "Up" semantics ("decrease nozzle-bed gap") stay consistent
  regardless of which physical part moves. Frontend untouched, single
  source of truth lives in the backend, keyed off the Printer.model
  column. Route Query description and docstring updated to spell out the
  new contract: distance is the gap adjustment, not the raw Z value.
