fix(add-account): apply selected algorithm and digits immediately

The algorithm and digits <select>s used v-model without the .number
modifier, so the in-memory entry held string values (e.g. "2"). The
generator compares the algorithm with === against the numeric enum, so
every non-SHA1 choice fell through to SHA1 until the entry was reloaded
from storage (which normalises the type). Add .number like the type
select already does.
