chore: Refactor authentication pass between subdomains (#1619)

* fix: Use get request instead of cookie to transfer token between domains

* Add domain to database
Add redirects to team domain when present

* 30s -> 1m

* fix: Avoid redirect loop if subdomain and domain set

* fix: Create a transfer specific token to prevent replay requests

* refactor: Move isCustomDomain out of shared as it won't work on the client
