fix(skore-hub-project): Make skore-hub-login more user-friendly

[auguste-probabl]

• Display

╭──── Skore Hub ─────╮
│                    │
│ Already logged in! │
│                    │
╰────────────────────╯

if user is already logged in (i.e. if token is found at /tmp/skore.token), rather than showing nothing. A better fix would be to show a log of "found token at /tmp/skore.token") I guess; let me know what you think.

• Display login URL in full, without line-wrapping, regardless of whether opening the browser succeeds. This way, the user can always fall back to copy-pasting the URL. Disabling line-wrapping is important because otherwise the URL is hard to copy-paste:
