Fixed: Allow Vault.set_setting() to pre-fill the keyboard prompt

Without a default, each retry in a login loop forces the user to
re-type the same value from scratch, which is frustrating enough
already, but even more so on a TV remote. Callers that need pre-fill
can now pass it explicitly; existing callers are unaffected.
