[MERGE] web: Various graph view improvements

This PR aims to bring several improvements to the graph view.

The main points are:
- custom tooltips in line mode to avoid problems with the Chart.js generic tooltips (those cannot
go outside of the canvas boundary and information is lost).
- tooltips when legend items hovered in case their texts were cut for reason of space.
