Fix address validation to work with Penumbra chains

[erwanor]

Trying to make transfers to Penumbra from anyhere in the interchain fails with this error on the main Skip app (not in the widget, curiously):

After digging, I learned that this started after this commit 8be4ad9 added address validation.

The source of the error is that Penumbra uses bech32m addresses.

I wish we could stop there, I would have pushed this simple change: d512a6e and carried on. Unfortunately, the diff has to be bigger because of interop issues with Noble mainnet.

Some context:

Penumbra addresses contain encrypted metadata. For a variety of reasons, this means that addresses must be encoded using bech32m.

1. Noble middleware first broke transfer with Penumbra chains, so we created a compat bech32 compatible address to make it work, with prefix penumbracompat1
2. Unfortunately, a second breakage happened and transfers with both the compat and ordinary privacy addresses broke, so we invented a transparent address format which is a bech32 address with a tpenumbra prefix (widget: add support for taddrs on penumbra #759)
3. Noble has deployed a good fix on their testnet, it should hit mainnet at the end of the month

In the meantime, this PR (along with #759) restores Skip functionality for Penumbra users. Once the Noble fix lands, I would be happy to straighten up the code here and in the fetch address logic.
