refactor: remove dead MessageMenu component and finish useAudioPlayer rename

MessageMenu was left in the v9 public surface even though the overlay path
no longer renders it; the source file carried a `// TODO: V9: Either remove
this or refactor it` note. Delete the component, its DEFAULT_COMPONENTS
entry, and its barrel re-export. The surrounding MessageMenu folder stays —
MessageActionList, MessageActionListItem, MessageReactionPicker, and
MessageUserReactions are the live replacements and remain overridable via
WithComponents.

Also finish the useAudioPlayerControl -> useAudioPlayer rename. The
byte-identical `useAudioPlayer.ts` was already being imported directly by
the internal callers (AudioAttachment, AudioRecordingPreview); only the
barrel still pointed at the old name. Flip the barrel and delete the dead
duplicate file.
