Fix web dashboard: exempt static assets from auth, fix user-mode uninstall

- Auth middleware now skips /static/ paths and WebSocket upgrades,
  fixing the blank splash screen (xterm.css and textual.js were 401'd)
- Uninstall script now properly stops and removes the user systemd
  service (~/.config/systemd/user/gniza-web.service) in user mode
