fix: re-enable Confirm Delete after a delete, so a second one needs no reopen (closes #335)

The password route disabled its Confirm Delete button before the decrypt
and never re-enabled it on success, so a second delete in the same popup
session found a dead button until the popup was closed and reopened. The
lost-password route re-enabled its own button in its leave hook, so the
two screens on the one screen behaved differently.

Both routes now reset the button through the shared finishDelete(), the
one path they both take, and the lost-password leave hook no longer
handles it separately. Tests drive a password-route delete and a second
delete in the same session; they fail against the prior head, where the
button stays disabled after the first delete.
