Looks good! Thank you! I left some comments inline - the main one is about parsing the account storage header.
To address it, we may need to add something like foreign_account_slot_names field to TransactionInputs and populate it after transaction execution.

Can we not use impl TryFrom<u8> for StorageSlotType instead?
I think the caller should first let byte = u8::try_from(felt) and then StorageSlotType::try_from(byte). Avoids having to test the impl twice, keeping it up to date in two places, etc.
