[IMP] project, hr_timesheet: profitability link

In order to improve the tracking of costs and revenues on projects,
this commit adds a "Profitability" link on the Kanban card of the
Project which appears for analytic accounting users when the
"Timesheets" / "Overview" link does not appear.

This link brings to the  tree view of the lines from the analytic
account linked to the project.
