[feature] display tokens, support metadata and remove beta

[rueshyna]

• display NFT on proposal card

  • bug fix for the fa2 data reading from metadata. the "to" is incorrect.
  • if the first transaction is NFT, tokens will be displayed by default. Otherwise, tokens are closed.

• handle metadata (TZIP16)

  • decode bytes if it's human readable. otherwise, remain the same.
  • rename matadata for lambda to note to avoid confused users.

Also even if io-ts and fp-ts look quite cool, adding them only for using it here is not worth it I think. Both libraries are quite heavy:

• fp-ts: 4.2mo
• io-ts: 460kb

I think there's tree shaking, so after compilation we only have the code we're using so it should makes it small, but I'm not sure it's worth it only for 1 component. If the plan is to incrementally refactor all the codebase with it, why not, but I don't think it's the plan for now

I did really think about it's good start for refactor, have test case for each of them and start closing to get rid of any. Anyway, I'm trying the powerful tool. so I used the same way to remove this two libs and generate test cases.
