Tournaments list

[Mateusz-Dobrzynski]

• Create a view for displaying/modifying tournaments.
• Each user should be shown only the tournaments they are permitted to see, i.e. only the ones within which they are given any roles.
• The infrastructure admin should be able to modify every tournament:
  • Create a new tournament,
  • Change a name and shorthand of an existing tournament,
  • Delete an existing tournament,
• Tournament organizers should be able to modify the tournaments they organize (in a card of a tournament they can modify, they should be displayed an options icon allowing them to make changes (edit and delete buttons).
• Every user should be able to click the tournament card to navigate to the tournament view.

To be discussed:

• Which edit icon do we wanna use?
  

Testing:

• Open the list as an infrastructure admin. Make sure you have full control,
• Open the list as an organizer of some (but not all) defined tournaments. Ensure you can only see and edit the tournaments you organize.
• One the list as a Marshall and as a Judge. Ensure you can only see the tournaments you are assigned to.
