launcher: GitHub's mark on Sponsor on GitHub, Sculk's card on every page, no border

dezer-x's launcher feedback, points 12 and 13:
- Sponsor on GitHub carries GitHub's mark (github.svg in the glass icons, drawn for Horizon:
  filled, its cat cut out by a mask).
- Sculk's card stays at the sidebar's foot on every page, Servers too; its border is gone (it
  still lifts under the pointer).
- On Servers, Sculk's banner sits right under the server, where it shows without scrolling past
  the server's tabs.
