refactor: share-intent ports for the composers

- SharedMediaResolver (rememberSharedMediaResolver) replaces the app's
  resolveSharedMedia(context, …); OnIncomingShare replaces the per-screen
  SEND-intent listeners in ShortNotePostScreen and GenericCommentPostScreen.
- ViewModels log their class via this::class.simpleName.
