feat: improve emoji panel UI and UX (#2383)

Added some basic fixes:

- Add backdrop overlay with outside-click-to-close 
- Reduce emoji button sizes to fit all emojis without scrolling
- Update styling to match player info panel theme

## Description:
I updated the emoji panel such as reducing the size so it fits on the
screen without scrolling for emojis, and ability to close the panel by
clicking outside of it. Previously you couldn't close the panel by
clicking outside of it, and this was inconsistent with the rest of the
UI. I also updated the styling to match the panel before that (the
player info panel).

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [ ] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [ ] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
