feat: merge server variants, remove GitHub OAuth HTTP (no DCR)

- Merge GitHub Docker + Enterprise into single definition with optional
  GITHUB_HOST input (empty defaults to github.com internally)
- Merge Grafana Self-Hosted + Cloud into single Docker definition with
  all inputs (URL required, username/password optional)
- Remove GitHub Remote OAuth (com.github-mcp-http) - no DCR support
- Fix GITHUB_HOST type from url to text (expects hostname, not URL)
- Keep Sentry npx + Self-Hosted separate (MCP_DISABLE_SKILLS=seer)
