[TOOL-2925] Dashboard: Redirect to Nebula app if team has access instead of showing waitlist page (#5894)

## PR-Codex overview
This PR introduces a check for `nebula` access in two `page.tsx` files, redirecting users to the Nebula web app if access is granted. It also maintains the existing login redirect functionality.

### Detailed summary
- Added a check for `nebula` access using `team.enabledScopes.includes("nebula")`.
- Redirects to `https://nebula.thirdweb.com` if access is granted.
- Updated login redirect paths in both `page.tsx` files.
