Code-wise looking strong, though a few possible unrelated changes in this PR.

Will do a functional test once I acquire some tokens on Base!

First pass - noticed accounts are in an infinite fetching loop after a full cache clear, which isn't the case on develop
https://jam.dev/c/785810ab-12f6-4b28-b424-1bb344a48595

This is caused by shapeshift/hdwallet#671 (which isn't present in develop currently since we didn't merge its web fren #6827) which this PR includes. Its web fren actually fixes the infinite loop issue - when the multichain snap isn't installed, trying to derive an account 0+ always derive the same account 0 pubkey (which has activity) meaning we fetch the "next" account number (really 0th) again ad vitam aeternam.

@kaladinlight, ideally #6889 needs to go in before but alternatively, if we don't want this to go first, we can also cherry-pick the <AppContext /> bits separately here.

All of the second pass testing below has been done after merging #6889 locally.

Been debugging this too @gomesalexandre - some additional info that might help:

• I'm getting the infinite fetching loop only on MetaMask (no Snap). Native is working fine.
• The state seems to get corrupted - e.g. if I switch back to develop I'm still in an infinite loop (though a fresh cache gets it working again)

Tested locally, LGTM

Happy to get this in after the snap bits go in as part of/before this

Derp, good catch and will work on getting #6889 in first with this to follow.

Retested locally, confirmed the previously spotted issue has been fixed and things are still happy on the BASE side of things 🎉
