[Bug]: JWT token missing

[youngancient]

After signing the message from the wallet, an API call is made to the backend, which may sometimes fail or take time. The goal of this issue is to ensure that the user waits till the JWT token is fetched.

@victuk, put a modal that overlays the screen, sort of like a glassmorphic loader, perhaps with a playful cartoon, like the Sonic Hedgehog SVG. This is because the time between signing a message and the backend returning the JWT is a lot, due to render sleep time and sometimes the user's internet. There's currently a signInStatus in the useAuthSignMessage hook
