staking token asset id

[turbocrime]

The asset ID for the UM token is (protojson) {"inner":"KeqcLzNx9qSH5+lcJHBB9KNW+YPrBk5dKzvPMiypahA="} or passet1984fctenw8m2fpl8a9wzguzp7j34d7vravryuhft808nyt9fdggqxmanqm

either const at build time or bundle the asset registry

stakingAssetId is already in the asset registry, or what do you mean by this issue?
https://github.com/prax-wallet/registry/blob/d2b78bd4c87c79829c5fd527e901bae31344a53a/registry/penumbra-testnet-deimos-7.json#L375

[turbocrime]

the registry was not yet bundled at the time i created this issue, this was in reference to discussion on #952

as the registry is bundled now it's less of an issue

staking token is still a special case, and perhaps should have a mechanism for acquisition other than the registry

Closing this as staking asset is available in registry package
