feat(auth): Base auth with plugins

- Add fastify to protect routes plugins (requireAuth: true)
- Simple Demo to show regular password auth (no 2FA/OTP nor remote auth)
- Currently supports: login, logout, signin
- OTP workflow should work, not tested
- Fixed convention for docker volumes (now all placed in /volumes/<name>)
