## PR-Codex overview
This PR updates the team management functionality in the `TeamRootPage` component by replacing the method for retrieving the team with a new function that checks for the last visited team or defaults to a standard team. This improves user experience by remembering the last team visited.

### Detailed summary
- Replaced `getDefaultTeam` with `getLastVisitedTeamOrDefaultTeam` in `TeamRootPage`.
- Updated the condition to check if a team is available.
- Changed the redirect URL to use the slug of the newly retrieved `team`.
- Added `getLastVisitedTeamOrDefaultTeam` function in `team.ts` to handle team retrieval logic using cookies.
