Wallets stored in local WalletStore are now bidirectionally synced with
the encrypted AccountVault on the server. On login, vault wallets are
restored to the local store; on wallet changes, local state is pushed
back to the vault. The server user profile wallet_address is also set
on login so mobile devices (without PRF) get the address via JWT.
