fix: MLS enabling setting [WPB-7097]

[borichellow]

What's new in this PR?

Issues

Wrong calculating if MLS is enabled for user or not.

Causes (Optional)

Nobody knows how it should work :)

Solutions

Fix it:

• if the MLS is enabled in settings AND MLS is in the supported protocols list,
• in all other cases MLS is disabled.

AND
in com.wire.kalium.logic.data.featureConfig.MLSModel make field allowedUsers nullable as it might be removed in the future.
