B OpenNebula/one#6638: Fix charting (#3133)

* Fixes handling of showback + accounting records
    - Previously only worked for groups
* Fixes rendering of multichart XAxis labels
    - Now uses a custom XAxis component to truncate long label names
    - Displays the full name on hover
* Fixes rendering of showback data in non-fullscreen
    - Now all 3 charts have sufficient screen space in both modes
