As a user I want to be able to see my available actions on the application after login

After logging into the application, users should be presented with a dashboard showing all available options for the user based on their permissions.

Tasks

Frontend
- [ ] A dashboard must be made following the login. There be a page header, clickable tiles for available options and the options should be separated based on type of option. E.g. Admin section, Volunteer section. The TLG logo in the header should always route back to this page and there should be a logout button in the header.

Backend

- [ ] GET request, given a user id, return all relevant roles and permissions assigned to the user.
