Remove stale DNS records: chimera, gopher, ecp-dev, and old verification TXT

Stale A records removed:
- chimera.pez.sh → 13.43.223.167 (AWS IP reassigned, now serving unrelated site)
- gopher.pez.sh → 83.94.248.182 (unreachable on all ports)
- 0o9lix.ecp-dev.pez.sh → 0.0.0.0 (placeholder, never valid)

Stale TXT verification records removed:
- protonmail-verification (mail is self-hosted now, not ProtonMail)
- keybase-site-verification (Keybase is effectively dead)
- MS=ms99554544 (Microsoft domain verification, no active MS services)
- google-site-verification (no active Google services using this domain)
- apple-domain (no longer using Apple services after GrapheneOS switch)
