Fire OS 8 (Android 11) devices typed as FIRETV never detect the current app

[ziopanna]

Device: Fire TV Stick 4K Max (AFTKRT), Fire OS 8.1.8.2. device_properties reports
sw_version = "11". Library androidtv 0.0.75, via Home Assistant 2026.9.3.

Symptom: with device_class = firetv the entity never leaves idle, even with Netflix
paused or playing in the foreground. app_id is empty.

Cause: in basetv/basetv.py every Android-version-dependent command (_cmd_current_app,
_cmd_current_app_media_session_state, and the other version switches at lines 138, 177-190,
222-234, 251, 276, 315-327) is gated on self.DEVICE_ENUM == constants.DeviceEnum.ANDROIDTV.
A device typed FIRETV therefore always falls back to the legacy command, which on Fire OS 8
returns nothing:

Command	Result on Fire OS 8.1.8.2
dumpsys window windows | grep -E "mCurrentFocus|mFocusedApp" (legacy)	no output
dumpsys window windows | grep -E "mInputMethod(Input)?Target" (Android 11 variant)	com.netflix.ninja/...MainActivity

With $CURRENT_APP empty, CMD_MEDIA_SESSION_STATE greps for nothing and the state falls
back to idle, although the media session is there (state=2, i.e. paused).

Workaround: configure the device as androidtv instead of firetv (and override the
power commands with CMD_TURN_OFF_FIRETV / CMD_TURN_ON_FIRETV). With that, playing /
paused and app_id are correct, and physical-remote play/pause is seen.

Suggested fix: choose the Android-version variants from sw_version for both device
types, i.e. drop the DEVICE_ENUM == ANDROIDTV condition from the version checks (or extend
it to FIRETV). Fire OS 8 is Android 11 and reports sw_version = "11".
