chore: repair @slidoapp/emoji-mart typings and allow React 19

In this commit we:
- stop generating dist typings that import from internal `components/HTMLElement`.
- export `PickerStyles` as `string` (no `bundle-text:` default export) and re-export it from the package entry.
- and expand `@slidoapp/emoji-mart-react` peerDependencies to include React `^19`.
