Issue #1774: Bluetooth remains on after switched off

Your system information

Steam client version: 1733265492
SteamOS version: 3.6.20
Opted into Steam client beta?: No
Opted into SteamOS beta?: No
Have you checked for updates in Settings > System?: Yes

Please describe your issue in as much detail as possible:
When Bluetooth is switched off on the Steam Deck, and then the device is put to sleep and woken back up, Bluetooth silently switches back on. This also happens on cold boot, and is with the LCD model.
Steps for reproducing this issue:

Disable Bluetooth in the UI
Put the Deck to sleep
Wake the Deck up
Turn on a previously paired Bluetooth device, and it will connect.

Expected:
Device does not connect, as Bluetooth had been switched off.
Result:
Bluetooth device connects.
Additional info:
Does the Bluetooth toggle in game mode just attempt to block new connections, instead of actually disabling the Bluetooth hardware? I suspect this because when disabling Bluetooth in game mode, it is still active in desktop mode. Whereas with WiFi, disabling it in game mode also disables it in desktop mode.
This can pose a serious issue when in environments that require devices to not emit radio waves, like on airplanes or near pacemakers. If turning on Airplane Mode or disabling these features doesn't actually disable them, that is a problem that should be addressed.

(The problem started in the regular version so I switched to beta hoping for a fix. The same problem persists)

Please describe your issue in as much detail as possible:
Expectation: Bluetooth devices should not wake the SteamDeck after being disconnected in UI, when Bluetooth is disabled in UI or when "Allow this device to wake Steam Deck" is disabled.
Reality: Turning off/on paired multi-point Bluetooth headphones wakes the SteamDeck even when the device has been disconnected in the UI and when Bluetooth has been turned off. This happens in both desktop and gaming mode and when "Allow this device to wake Steam Deck" is disabled.
Headphones Google Pixel Buds Pro 1 with multi-point connected to phone and SteamDeck
Steps for reproducing this issue:
Wakes SteamDeck when turning headphones on (desktop mode):

Pair/connect multi-point Bluetooth headphones to SteamDeck
Disconnect the headphones in the UI
Disable Bluetooth in the UI
Put SteamDeck to sleep
Turn off headphones/put in case
Turn on headphones/take out of case
SteamDeck wakes up and stays awake trying to connect to headphones

Wakes SteamDeck when turning headphones off (desktop mode):

Pair/connect multi-point Bluetooth headphones to SteamDeck
Disable Bluetooth in the UI
Put SteamDeck to sleep
Turn off headphones/put in case
SteamDeck wakes up and stays awake trying to connect to headphones
