feat: switch avatar imager to epicnabbo.nl with figure conversion

- Update imager to use epicnabbo.nl by default with effect=14 and img_format=apng
- Add figure string converter (old Habbo format -> epicnabbo.nl short format)
- Update avatarImageUrl to auto-convert figure strings
- Update online-users-widget to use new avatarImageUrl
- Add tests for imager and figure conversion
