fix: remove exception for showing "Apps are active" info - WPB-24961

WPB-24961 [iOS] Apps active banner not visible

Issue

Currently we'll only show the banner "Apps are active" in a conversation if there are more participants than the self user and the app/bot.
This PR changes the logic and now we will always show the banner if any app is present.

Testing

Add an app to a conversation and see that the banner is visible.

Pull request overview

Updates the data-model computation for ZMConversation.externalParticipantsState so that group conversations report .visibleApps whenever an app/bot participant is present (including the “self + single app/bot” case), which enables showing the “Apps are active” banner more consistently.

Changes:

• Removed the special-case that returned an empty external participant state when the only other participant in a group was an app/bot.
• Adjusted the inline comment describing the remaining exception for non-group conversations.
