Add Message/EngineMessage.effectiveMedia (= message.media when non-empty, else
richText.instantPage.allMedia()) and route the media-consuming sites through it
so a rich message's instant-page media participates in the same pipelines as
normal message.media: shared-media grids/file-rows, search media grid, gallery
open + item nodes + footer, the peer audio/voice playlist, secret-media preview,
resource-by-id resolution, recent downloads, downloaded-media store, delete-time
resource cleanup, cache-usage stats, the in-chat download manager, and the
context-menu / share actions (Save to Camera Roll, copy image, save audio/music
to files). For normal messages effectiveMedia == message.media, so each swap is
behavior-preserving; rich messages render their own bubble via
ChatMessageRichDataBubbleContentNode (not the text/file bubbles), so those paths
are deliberately untouched, as are the forward path (the attribute travels with
the forward) and the markdown-based rich-edit path. First-media scope for now.
See docs/instantpage-richtext.md for the full architecture + invariants.

Render and play InstantPageBlock.audio in the InstantPage V2 renderer
(rich-data message bubbles + the rich send preview), where audio was
previously an inert grey placeholder.
- New InstantPageV2AudioContentNode replicates the standard music message
bubble (ChatMessageInteractiveFileNode's music layout): a SemanticStatusNode
control (album art via playerAlbumArt + play/pause) with a download/progress
overlay, title + "duration · performer" lines, exact fonts/colors from
theme.chat.message.{incoming|outgoing}. Tap is driven by a
UITapGestureRecognizer (ASControl .touchUpInside is cancelled by the chat
ListView's gesture system). V1's InstantPageAudioNode is unchanged.
- Playback runs on InstantPageMediaPlaylist with a discriminated, message-scoped
InstantPageMediaPlaylistId (.instantPage / .richMessage) so concurrent
rich-message audio bubbles don't collide; the big control's play/pause comes
from filteredPlaylistState, the overlay's download/progress from
messageMediaFileStatus, and fetch goes through the fetch manager.
- Rich-message audio fetches via a MessageReference (threaded through the V2
render context) instead of the synthesized webpage; FetchedMediaResource's
.message revalidation arm now also searches RichTextMessageAttribute instant
pages, so a stale instant-page audio/image reference can recover. Corrected a
dormant inverted InstantPagePlaylistLocation.isEqual.
- New .mediaAudio laid-out item + layout/reveal-cost arms; the audio block lays
out full-width at the file node's music normHeight.
