ScreenTinker f5ca26ae2d fix(socket): offline debounce + truthful single-device command feedback
Two dashboard-accuracy improvements for issue #3.

Disconnect debounce (5s):
- Brief transient flaps (Engine.IO ping miss, eviction-then-reconnect,
  Wi-Fi blip) no longer immediately flip the device to offline in the
  dashboard. Disconnect handler now defers the offline transition;
  register handlers cancel the pending timer if reconnect lands in
  window.
- Existing stale-disconnect guard kept as fast-path for the eviction
  case (no timer scheduled at all when the active heartbeat conn is
  already a different socket).
- Re-check at timer fire compares socketIds: aborts only if a
  GENUINELY DIFFERENT socket reclaimed the device. Just the closing
  socket's own (not-yet-cleaned-up) entry is treated as stale and
  proceeds with offline transition.
- Server-restart mid-grace is handled by the heartbeat checker safety
  net (existing component): any 'online' row with last_heartbeat
  older than heartbeatTimeout gets marked offline on next sweep.

Truthful single-device command feedback:
- dashboard:device-command handler now checks deviceNs.adapter.rooms
  for an active socket before emitting (matches the group-command
  route's pattern).
- If room is empty, falls through to commandQueue.queueCommand (lazy
  require - if commit C is reverted, MODULE_NOT_FOUND is cached and
  every subsequent call gets consistent queued=false behavior).
- Returns three-state ack to caller: { delivered, queued, reason }.
- Server log line was misleading - now logs 'Command delivered to
  device X' vs 'Command for offline device X (queued=true/false)'.

Frontend:
- sendCommand() takes optional callback. Without one, fires-and-forgets
  (no behavior change for non-wired callers). With one, uses Socket.IO
  .timeout(5000).emit so the callback always fires (ack or no_ack).
- Six device-detail command buttons wired to three-state toasts:
  reboot, shutdown, screen_off, screen_on, launch, update.
  - delivered: green/success toast (existing localized message)
  - queued: amber/warning toast (new generic message)
  - no_ack: red/error toast
  - fallback: red/error toast
- Two callers intentionally left fire-and-forget:
  - window._sendCmd (generic remote-overlay keypress/touch helper)
  - enable_system_capture (has its own visual state machine; out of
    scope for this commit)

Three new i18n keys (en.js only; other locales follow later):
- device.toast.command_queued
- device.toast.command_undeliverable
- device.toast.command_no_ack
