maziggy e2df0fc601 fix(ams): physically-empty slots report state=9 and render distinctly from reset slots (#1322 follow-up) ...

Two-part fix for the #1322 follow-up by @RosdasHH.

  Data layer.
  The previous narrow heuristic in printer_manager.py only caught
  the bare {"id": N} payload firmware sends right after a printer
  restart. In steady-state operation — and on the more common
  post-Reset-Slot path on P1S and A1 Mini BMCU — firmware sends a
  populated payload and signals emptiness via the tray_exist_bits
  bitmask. We already parse that bitmask and use it to wipe stale
  tray_type / tray_color / tag_uid fields, but never touched the
  state field, so downstream readers (printers.py API serializer,
  inventory.py's tray_state in {9, 10} short-circuit, AMS card)
  saw state: null and had to guess from absent payload fields.

  Fix lifts tray["state"] = 9 (int — not "9"; inventory.py:1358
  uses == not `in {...}` so a string would silently miss and the
  reporter's deadlock would come back) to the outer `if not
  slot_exists` branch, so the bitmask path now writes the
  canonical "no spool" code for every empty slot regardless of
  stale fields. The narrow heuristic in printer_manager.py:797
  stays as belt-and-suspenders for any MQTT path that doesn't
  flow through _handle_ams_data.

  UI layer.
  With the data flow now consistent, the AMS slot card renders
  physically-empty slots distinctly from reset slots, per
  reporter's mockup. New helper getEmptySlotKind(tray) returns
  "physical" (state ∈ {9, 10}), "reset" (any other empty state),
  or null (loaded). The inline label below the slot circle reads
  "Empty" for physical and "Reset" for reset; pre-fix both showed
  an em-dash. FilamentSlotCircle gains an emptyKind prop that
  picks a quieter dashed border colour for reset slots so the
  visual hierarchy reads loaded > reset > physically empty.
  EmptySlotHoverCard gains a kind prop and switches between
  "Empty slot" and "Slot reset — no spool assigned".
