feat: as an admin I can add alert on a path

[caro3801]

Backend

• Add annotation with proper permissions on the alert path endpoint
  refactor: update note to path banner and add PUT, DELETE PathBanner endpoints #2105

Frontend

• implement proposed design in design: as an admin I can add an alert on a path #1921
• check role on the frontend side (guard on page?) if the user is allowed to see it.
  I had to make some changes to allow route design consistent with the route guard. Meaning that the form has to go in another page see feat: add path banner management datashare-client#432
