Rework Analytics page

[KralMarko123]

The analytics page needs to be reworked in order to address some issues that are currently present. An approach and design that can be used as a point of reference can be found at the following figma link. The two main issues that this rework should fix are:

• Speed (the current analytics is really slow since it loads all groups and datasets initially)
• Stop using Highcharts and find another charting library
