[Faculties] Tweaks and polishing

[rikurauhala]

• Combine Students by starting year and Progress tabs
• On the Progress tab, use an Accordion for each of the education levels
• Add bolding the active option back to MUI toggles
• Display all toggles vertically in all cases for consistency
  • It could be a good idea to make a reusable ToggleContainer component
• Include graduated students in the progress charts
  • See Class statistics for an example
  • Also, change the default sort order to descending in Class statistics for consistency
• Fix the "Show percentages" toggle formatting
  • The percentages don't quite seem to fit in the cells
