Singapore schedule: tone strip, GitHub socials, ChilliCream sites

- Wrap the schedule block in bg-neu-50 / dark:bg-neu-50/50 with full
  top + bottom borders so it reads as its own section.
- Drop the section's vertical padding (!py-0) — the inner border-x
  block handles spacing now.
- Add GitHub to the SocialIcon registry (re-uses the existing
  GitHubIcon from @/icons), wired into SocialIconType.all.
- Pascal Senn and Michael Staib get GitHub + ChilliCream website
  links. Akshat Sharma keeps LinkedIn only — couldn't confidently
  confirm a GitHub for him from public sources.
