Track draft ID in composer state machine

Adds draftId to ComposerState so that editing an existing draft and
saving it again updates the draft rather than creating a new one.

- Add draftId?: string to ComposerState type
- Set draftId when restoring from draft via restore_from_draft action
- Pass existingDraftId to save functions from composerState.draftId
- Add PageX icon for empty drafts state
