Create Admin dashboard

[awesominat]

Accessed through /admin it should be a dashboard (UI here isn't too relevant, this is mainly for admins/maintainers) that allows for two functionalities:

1. assign projects to users and create projects
2. assign teams to users and create teams

Both of the above should be coded such that other pages in the website can receive information about all teams, a specific team (and the same for projects)

This also requires the creation of the schema projects and teams follow. For this, please follow the current schema the repository has for teams and projects (found in the schemas folder)
