feat: begin integration of IBC with transfer module

[emccorson]

This is the first attempt at integration the prototype IBC form with the transfer module.

Some caveats:

• Only transparent transfers are working
• We still need to set the channel ID manually for now
• Assets will take some time to load after the chain has been selected

Testing

Namadillo settings

Indexer: https://indexer.public.heliax.work/internal-devnet-44a.1bd3e6ca62
RPC: https://proxy.public.heliax.work/internal-devnet-44a.1bd3e6ca62

IBC transfer to Namada settings

Source channel: channel-4353
Destination channel: channel-0
(Note: destination channel is only needed for transfers to shielded accounts)

Instructions

1. Go to Namadillo settings -> advanced, and make sure "Enable Testnets" is checked
2. Go to /settings/features and check "IBC Transfers"
3. Make sure you have ATOM for the Cosmos testnet (theta-testnet-001) in Keplr
4. Go to the Namadillo IBC Transfer page
   a. Enter the source and destination channel IDs as above
   b. Select the Cosmos testnet (the one called "[DEPRECATED] Cosmos Hub...")
   c. Wait for assets to load and then select "Cosmos"
   d. Enter an amount
   e. Select "Transparent" for the Namada account
   f. Click "Submit" and approve the Keplr popup
5. After a few seconds, check your ATOM was received in Namada with:

namadac balance \
    --owner <your address> \
    --token transfer/channel-0/uatom \
    --node https://proxy.public.heliax.work/internal-devnet-44a.1bd3e6ca62

I think we'll still want to display an asset even if we don't have information for it in the asset list. For example, NAM isn't going to show up in the asset list (although actually maybe we could add it), but we still want to support transferring NAM over IBC.

The easiest thing to do here might be to change TransferModule to specify the properties it needs for assets e.g. instead of Asset, use Pick<Asset, "name" | "base"> or something like that. Then we can more easily construct what the TransferModule needs in these cases.

I think this might be a bigger problem, because if the asset is not known in the asset list, maybe we will need to query some of its info from somewhere. Can we separate this into a new issue?

[emccorson]

This is cool! I think you're right about using the RPCs sequentially instead of randomly. Just from brief testing, it seems hit or miss whether an RPC will actually work (and I'm hoping they are ordered roughly by reliability).

I'm able to do an IBC transfer 🚀

I believe we can do more upgrades on future PRs
