feat: editor coming-soon bumper + embedded Premiere panel downloads

- Editor: overlay Coming Soon screen over NLE timeline (code preserved,
  bumper sits at z-index 100 with backdrop blur). Links to download
  ZXP and Windows installer directly from the bumper.

- Settings → Capture SDKs: new Premiere Panel section lists v1.0.0
  and v1.0.1 with ZXP + Windows Installer download buttons.
  Both releases embedded as static files in web-ui under /downloads/.

- nginx: /downloads/ location serves files as Content-Disposition
  attachment with 24h cache.
