A rejected password was reported three different ways depending on which screen
you were on, including the fragment "Wrong password." which is not a sentence.
All six decryptWithPassword call sites now show the same full sentence.
Strings only -- a wrong password still fails closed on every screen and still
resolves no pending approval.
A test pins the invariant per call site: each decryptWithPassword call is walked
out to its enclosing try and forward to that block's catch, and the prose shown
there must equal the canonical sentence. Per-file matching was not enough, since
a file with two call sites kept passing while one of them diverged.
