Add mobile-responsive web template, gniza uninstall command, fix web commands for user mode

- Custom textual-serve template with viewport meta tag, full-viewport
  terminal sizing, and auto font-size for mobile (<768px)
- Fix web install-service/remove-service/status to handle user-mode
  systemd (systemctl --user) alongside root mode
- Add 'gniza uninstall' command that runs the uninstall script
