fix(web): port check, process isolation, startup diagnostics

- web-publish: check port availability before starting, show which process
  holds it; run httpd -t on startup failure for diagnostics
- All scripts: filter httpd processes by path (Resolve-Path match) to avoid
  killing or misidentifying a global Apache installation
- web-info: warn about foreign httpd processes
- web-stop: only stop our Apache instance
