Only queue image uploads for sleeping deep-sleep displays

[Copilot]

Queued image delivery was being triggered whenever a display was not connectable, even if the device did not use deep sleep. This change narrows queuing to the intended case: a deep-sleep-capable display that is currently asleep; all other displays upload immediately.

• Behavior change

  • Gate deep-sleep queuing on deep_sleep_time_seconds > 0.
  • Preserve the existing wake-up flush path for queued uploads when a sleeping display becomes connectable again.
  • Stop applying the fallback expiry path to devices that do not advertise deep sleep support.

• Why this matters

  • Non-deep-sleep devices should not defer uploads just because they are temporarily not connectable.
  • The queue now represents exactly one state: “device is sleeping and expected to wake within its configured deep-sleep window.”

• Test updates

  • Replace the zero-deep-sleep fallback test with coverage for immediate upload when deep sleep is unsupported.
  • Keep the existing queued-upload expiry and wake-up behavior unchanged for actual deep-sleep devices.
