[IMP] project: add "view tasks" button in project list view

In this commit we introduce a button in the project list view
which, if clicked, redirects the user to the project task
kanban, where they can see the project's tasks.

This change gives the user the posibility of directly viewing
a project's tasks from the project list view without needing
to go through the form view, thus increasing efficiency.
