Fix Apple TV keyboard focus binary_sensor missing on cold start

[kroehre]

Proposed change

The Apple TV keyboard focus binary_sensor subscribes to SIGNAL_CONNECTED,
but async_first_connect already awaits the connection (and dispatches the
signal) before platforms are forwarded, so the initial signal is always missed
on cold start. This matches the symptoms in #170075: most users never see the
entity; one user observed it appearing only after reconnect events.

Verified end-to-end on Apple TV 4K (gen 3), tvOS 26.4: entity appears after
fresh pairing and persists across HA restart.

Pull request overview

Fixes a cold-start race in the Apple TV integration where the keyboard focus binary_sensor misses the initial SIGNAL_CONNECTED dispatch (sent during async_first_connect) and therefore is not created until a later reconnect.

Changes:

• Update the Apple TV binary_sensor platform setup to also handle the “already connected” case (create entities immediately if manager.atv is present).
• Add a regression test ensuring the keyboard focus binary_sensor is created during initial config entry setup.

File	Description
homeassistant/components/apple_tv/binary_sensor.py	Creates the keyboard focus entity when the manager is already connected, avoiding missing the early connection signal.
tests/components/apple_tv/test_binary_sensor.py	Adds regression coverage for entity creation on cold start.

Hi @kroehre, thanks so much for the fix. The binary sensor is now correctly added to the device. Just a quick question, I’m not sure if the bug is on my end or in the backend. The sensor state doesn't respond when the keyboard is in focus. The correct state only changes after a hard reload of the integration entry. Similarly, when it's not in focus, it doesn't switch to off.

What is the actual response? Is there something I need to configure in the Apple TV settings?

@ngocjohn Take a look at the discussion on the issue. There is an issue and open PR on the underlying library that addresses that. #170075 (comment)
