i18n(android): the interface speaks English, like the desktop app

It was in French because the conversation is, and I never asked. The desktop
app the client mirrors says Add field, Attach file, Show previous versions -
someone moving between the two would notice the seam.

Every visible string moved: buttons, statuses, detail row captions, log lines
and the biometric prompt, plus the messages the modules surface through
LastStoreError and LastBiometricError.

Code comments stay in French. They address the author, not the user, and that
is already the language of CLAUDE.md and much of the repo.
