feat(P3-6): configurable composer toolbar buttons

Each button (Format, Emoji, Sticker, GIF, Location, Poll, Voice,
Schedule) can be individually hidden in Settings → Editor.
All default to on, stored in composerToolbarButtons object.
getSettings deep-merges the nested object so new buttons default
to true for existing users with saved settings.
