[IMP] project: add project color in task calendar filter

This commit colors the project filter checkboxes on the right side panel
of the task calendar view with the color of the corresponding project.

It also changes the color of the events in the tasks in the calendar so it
uses the color in the project in the view "All Tasks", and the color of
the tasks in a calendar view of a specific project.

Finally, it adds some colors to tasks in demo data to better showcase
that feature.
