Feature request: Statistics page

[AXeL-dev]

It would be interesting to have a statistics page with the following data measures:

• number cards:
  • total number of viewed videos (+for the current week, +for the current month?)
  • total number of watch later videos (+for the current week, +for the current month?)

:bulb: For the current week/month, it could be just an indicator for how much the number was incremented/decremented compared to the previous week/month.

• pie/bar/line charts:
  • pie chart with viewed/watch later videos per channel
  • bar chart with the number of viewed videos per month for the current year
  • ranking of most viewed channels for the current month?
