fix(audio-rooms): switch NestsServersEvent to kind 10112 (nostrnests claim)

nostrnests's reference README under "Nostr Integration" already declares:

  kind:10112 — User-published audio server lists

We initially picked 10062 (mirroring BlossomServersEvent's 10063) without
spotting that prior claim. Switching to 10112 so a single replaceable
event surfaces in both Amethyst and nostrnests's web UI without
collision.

No migration cost — no users have published kind 10062 yet.
