fix(assign-spool): refresh printer status after assignment so card updates without manual Force-refresh (#1414 follow-up)

Reporter (@snozzlebert on A1 mini external slot) saw the
  Filament page Location column update correctly after Assign
  Spool, but the Printer card kept showing "Empty slot" until
  they manually pressed Force-refresh. MQTT command was going
  through fine; gap was client-side.

  AssignSpoolModal's two onSuccess callbacks invalidated the
  inventory / slot-assignment queries but never invalidated
  ['printerStatus', printerId] and never issued a pushall. For
  Bambu RFID-tagged spools the printer echoes the new tray_type
  on its own; for non-RFID spools and A1 mini external slots
  the firmware doesn't volunteer that state change.

  Added nudgePrinterRepublish() helper called from both onSuccess
  paths: api.refreshPrinterStatus(printerId) to issue the pushall
  (same call the Force-refresh button uses) plus invalidate
  printerStatus so the refetch lands. Refresh failures are
  swallowed — the assignment itself succeeded; a stale-cache
  nudge that didn't go through shouldn't surface as "assign
  failed". Same pattern as ConfigureAmsSlotModal since #1235,
  with the extra pushall because assign-spool affects firmware-
  side state.
