fix(printer-card): confirm before HA entity toggle on printer card (#1260)

Smart plugs with "Show on Printer Card" enabled appear as a chip in the
  HA-entities row below the main plug controls. One click cut power to the
  printer instantly — including mid-print — while the main Off button right
  next to it already routes through a ConfirmModal. The HA-row chip was
  added later and skipped the same gating.

  Branch on entity type: script.* entities keep firing instantly (fire-once
  triggers, not power switches — confirming each click would be annoying),
  but switch/light/anything-else entities now open a ConfirmModal first.
  Reuses the same variant="danger" + running-print warning copy as the
  existing power-off confirmation when status.state === 'RUNNING'.
