Introduces channelinfo.h in the AAC module to provide a clean, Qt‑friendly data structure for representing TeamTalk channels. This struct is used by the AAC‑native UI to receive typed channel data from the backend during channel enumeration. It keeps AAC UI logic self‑contained, avoids coupling to legacy QtTeamTalk widgets, and prepares the UI layer for future AAC‑specific metadata.
I will work on replacing the pseudocode blocks with the real enumeration pattern in the C API (whatever functions in TeamTalk.h expose the channel list in 5.19) later.
I am now thinking about the AAC-native UI's UX layer explicitly, which is why this screen, and the next few commits that come with it, will be in place.
