Escrow re-auth answers in the box language; a stacks test no longer writes into its source folder

Both fixed without a row (size rule): login.msg.wrong_password for the escrow re-auth
(TestEscrowReauth_WrongPasswordInTheBoxLanguage, red-proved); cmdManager gets its own DataDir (the update
journal went into internal/stacks/, and the R-578 source walk tripped on it once).

+  `login.msg.wrong_password` (same Hungarian bytes; English on an English box), `TestEscrowReauth_WrongPasswordInTheBoxLanguage`,
+  red-proved. A stacks test (`cmdManager`, R-717) wrote the update journal into its package folder (an empty DataDir),
+  where the R-578 source walk running in parallel failed once — it gets its own DataDir; a probe that panics on an empty
+  DataDir then ran the whole stacks suite green.
