fix: say a second wallet's password is separate when one is chosen (closes #374)

The add-wallet screen offered only "Choose a password" while each wallet
keeps its own encrypted secret, so a second wallet silently accepted a
password different from the first with nothing marking it as separate. A
note now appears on that screen when the profile already holds a wallet,
saying each wallet has its own password and this one need not match any
already in use. It is shown only then — the first wallet has no other
password to differ from — and is decided on screen entry, so it does not
move the password fields. It promises no recovery or reset, staying
consistent with the no-password-reset design.

 # Completed Steps
 
-- 2026-09-21: The test recovery phrase no longer survives in a release bundle,
-  and the committed-key guard matches by content
-  ([#351](https://git.eeqj.de/sneak/AutistMask/issues/351)). `DEBUG_MNEMONIC` in
-  `src/shared/constants.js` is now behind the `__BUILD_DEBUG__` define, so a
-  release build folds the phrase to `null` and no emitted bundle carries it; it
-  used to survive as dead text because `module.exports` keeps the const alive.
-  `script/verify-build` now fails a release build if the phrase appears in any
-  emitted file, so the fold cannot silently regress. `tests/extensionId.test.js`
-  scans the content of every tracked file for a PEM private-key header instead
-  of matching filename extensions alone.
 - 2026-09-21: A transaction response is honoured only for a transaction
   approval, and the three remaining approval-settlement paths are pinned
   ([#262](https://git.eeqj.de/sneak/AutistMask/issues/262)). The liveness fix
