fix(imaging): make avatar and badge images resilient to upstream outages

Browse Source

- Add persistent disk cache for rendered avatars/badges (storage/imaging)
  so repeats never touch the flaky local renderer and cached renders
  survive upstream downtime
- Serve cache-first with stale-on-error; cut primary/fallback timeouts
  from 10s/6s to 4s/4s so failing images cannot stall pages
- Avatar proxy now returns a graceful 200 silhouette instead of 502 when
  no renderer can produce a figure, so no broken-image glyphs appear
- Badge endpoint becomes a caching proxy trying configured CDN, public
  Habbo CDN and local /swf copy in order, and drops the fragile IP rate
  limit that could blank badge streams
- Route all site badge images (profile, me, badges, apply pages) through
  the cached proxy instead of hot-linking images.habbo.com
