Consistent & meaningfull styles & colors

For now, the colours are the following:

• Data types:
  • Modification = sky
  • Guide = lime
  • Target = amber
• Modification types:
  • Am = lime
  • Um = red
  • Cm = orange
  • Gm = yellow
  • Ψ = violet
• Other:
  • Primary colour = #4F46E5 (a dark violet, default PrimeVue one)
  • External references colour = red

This diversity can create confusion, especially as some colours are reused for different purposes (e.g. lime or red). There is no clear colour scheme or theme in general, except the PrimeVue one. The goal is to stick with some few colours as a theme, keep modifications colours (maybe refine them to be either more distinct, or categorised by type - 2'-O-me or Ψ), and remove useless colours (notably the ones corresponding to data types, which are sort of useless with the name of the data.

The pills in the details pages can take many space e.g. on target pages which have many linked data, so a way to collapse the section has to be implemented.

Eventually a colour-blind mode which toggles some symbols.

Consider using a light grey (slate-50) background ?
