Changes to fees & referral page to support new fee model

[JonRay15]

The Chore

The Suzuka Castle release will introduce a new fee mechanism in Core.

Fee page

• [ ] One card shoudl just show the network fees, including the new treasury and buyback components, all these come from the network params and are easy
• [ ] Maker rebate info
  • [ ] Current tier shoudl come from partyDiscountStats
  • [ ] #7013
  • [ ] Volume to next tier find the fraction needed for teh next minimumPartyMakerVolumeFraction on currentVolumeRebateProgram and show the gap in % to get there
• [ ] Taker volume discount
  • [ ] Current tier shoudl come from partyDiscountStats
  • [ ] Current volume shuld come from runningVolume on volumeDiscountStats for the current epoch
  • [ ] Volume to next tier find the volume needed fro the next minimumRunningNotionalTakerVolume up on currentVolumeDiscountProgram and show the gap to get there
• [ ] Referral discount
  • [ ] Current tier shoudl come from partyDiscountStats
  • [ ] Current running volume shoudl come from referralSetRunningNotionalTakerVolume on referralSetStats
    • [ ] You may be able to do this simply by adding a partyId
    • [ ] Or maybe you need to first query referralSetReferees for referee = partyId to find the referralSetId.. then use that
    • [ ] We will need to set up some tests to check this because I think the referrer doesnt get the discount but the referee does, so we need to make sure we're showing the right info
  • [ ] Volume to next tier find the volume needed for the next tier up on currentReferralProgram and show the gap to get there

• [ ] Next section should be the fees by market which now focuses on the below and SHOULD all be available on the new partyDiscountStats API
  • [ ] Show discountedTakerFee as "Taker fee"
  • [ ] Show undiscountedTakerFee - discountedTakerFee / undiscountedTakerFee in brackets
  • [ ] Show baseMakerFee + userMakerRebate as "Maker rebate"
  • [ ] Show userMakerRebate in brackets

• [ ] Show the full grids of the programs for use as reference, likely these will need to move to just stacked on top of each other since they are too large now, also probably remove the colours as these are now not the focus
• [ ] We're basically just goiing to be showing the full content of the APIs for
  • [ ] Taker volume discount (currentVolumeDiscountProgram)
  • [ ] Referral program (currentReferralProgram)
  • [ ] Maker rebate boost (currentVolumeRebateProgram)
