Rewards history UX tweaks

[JonRay15]

The Chore

The reward history table currently sums up rewards over a range specifed in the selectir. This is sort of nice but sort of not.... suggestions

Tasks

• [ ] Add a toggle for "show details" vs "show summary"
  • [ ] In show detail mode we want to see the epoch breakdown, so could
    • [ ] Just duplicate the entire grid for each epoch and show a header, and allow paging between them, including moving to a specific epoch if the user wants to
    • [ ] Add the epoch to the table and group them up
    • [ ] Add the epoch to the table and just sort them
  • [ ] In show summary mode follow existing behaviour
• [ ] You cannot currently type an number into the TO selector so if you want to move that a long way you have to click many times
• [ ] There's also some glitching when you type

Look at options during implementation and see what we can do.
