Trema: Pagination des demandes

Les demandes sont limitées à environ 25 dans le drop down, ce qui ne permet pas de mettre à jour toutes les demandes. Il faudrait aussi une fonciton pour effacer les demandes.

Start by locating the request dropdown and the code that updates requests, then trace how the current limit of about 25 is applied. The work is done when all requests can be reached through pagination and a function for deleting requests is available; no file or test is named in the issue.
