Tasks UI changes proposal

[stecb]

I think we can further improve the tasks UI, as a couple of things are a bit confusing to me:

• [ ] Main card
  • [ ] the play/time can be separated (time can be put on the header)
  • [x] we should add a chevron button to be able to see you can open to check/see the time entries
  • [ ] I'm not sure I understand the colors of the "tags", maybe we can just put them as "default". The colors really don't make a lot of sense, IMHO

• [x] Time entry
  • [x] Add a bit more padding (i.e. size(2) => 16px)
  • [x] Icons don't make a lot of sense, I'd remove them
  • [x] Having the date/time and then the total time (hours/mins) in 2 separate lines is redundant. I'd keep them in 1 line

@gianlucadonato if you add height: 100% to the time entries cards, they will have the same height and it IMHO looks cleaner :)
