Serve avatars from site's own /imaging endpoint instead of habbo.com

- Change default public imager URL from habbo.com to /imaging
- /imaging and /api/imaging/avatar now proxy from upstream (habbo.com) instead of redirecting
- Add resolveUpstreamBase() to separate public URL from upstream URL
- Update admin settings default and description
