EnterCode Signup working

- After fetching join code in EnterCode(), it sets networkId attribute on "signup-" (Signup.js)
- Signup.js then includes the attribute in the call body
- Modified all calls to /signout, /profile, /login, /signup to be prefixed by '/auth'
- Added '/auth' to vite config file
- Modified final "else if" statement in .attr in quill.js to return `this.getAttribute(arg1)` instead of `this.getAttribute("")`
