Issues

When a personal user migrates to a team account, the "Your Team" input field allows the user to enter only spaces as the team name and proceed with registration. This results in invalid or meaningless team names, which should not be permitted.

Solutions

Modify the check for enabling "continue" button to also check whether the name is not blank.
Trim all excessive spaces at the start of end of the name.
