refactor: improve EmojiPicker type safety and code organization

- Add proper type declarations for emoji-picker custom element
- Define EmojiPickerElement and EmojiClickEvent interfaces
- Replace @ts-ignore with proper TypeScript types
- Separate dataSource initialization into its own useEffect
- Use local emoji data from emoji-picker-element-data
