style(audio-rooms): import-and-use instead of inline FQNs

Replace inline `com.vitorpamplona.…` references in code + KDoc with
imports + the short class name across the audio-rooms surface. KDoc
references that would have introduced an `ui` → `model` import cycle
(e.g. NestsServerListState referring to CreateAudioRoomViewModel) are
demoted to plain text instead of clickable `[Class]` links.

No behavioural change.
