Claim hooks 2 - ready to fetch

[alfetopito]

Summary

Adapted fetch functions to expected document format coming from future claims repo

• Modded useUserClaims

• Using fake data but at a different stage

• Converting string types to enum types (Airdrop -> 0)

• Renamed button Claim vCOW to vCOW

• Made vCOW button always visible

  To Test

1. Connect wallet on rinkeby
2. Click on vCOW button
3. Click on claim
4. Execute tx

• Claim will be performed and claimable amount will be reduced

Note: Each claim can be done only once, so if you can't claim, try using a different claim index in this file

Background

Optional: Give background information for changes you've made, that might be difficult to explain via comments

I tried the test plan and after I connected my Metamask it worked, here is the transaction. ✔️

I can't say much about how React-specific things are used, but everything contract related looks good to me.

FYI, I rebased with latest from claim branch which includes Michel's components, thus the claim action no longer works.
Since Federico tested and it's working, I'll merge as is.
Feel free to add comments afterwards and I'll address them in follow up PRs.
