Save selected period in project dashboard

Now when you change the date range in the date picker, the dates will be saved in your browser session.

This means that when you change to another project in the same work session the dates will be kept, avoiding having to change to the desired period each time you view one (especially tedious if you have many projects).

However, if, for example, you come back the next day, the system will revert to showing 1 month by default.

Any feedback you may have is appreciated:
