Add possibility to view spent time/done tasks sorted by week/day

[corebots]

Time trackers like Clockify group spent time on project/task in a week view. This makes it easy to see total time spent per day per week which is helpful when booking hours into other systems like YouTrack at the end of the week.

I agree it's a necessary feature. Currently, you can see time spent per day by clicking on project duration button alongside project name. It's not enough and more detail will be in Calendar page.
