  npm audit fix

Some issues need review, and may require choosing
a different dependency.

How is it going? This will finally protect all webapps, great addition :)

Coupled this with Traefik for forward auth! AMAZING!

@NorthantsAndy I'm able to get as far as you. Don't know if you've seen this repository: https://github.com/gtsatsis/authentik-bare-metal?tab=readme-ov-file#authentik---bare-metal-install but maybe it can help us get over the hump! Authentik via lxc would be amazing.
