feat(settings): redesign encrypt & change-passphrase modals onto reference design

Migrate the Encrypt Wallet (3-phase) and Change Passphrase dialogs in
renderEncryptWalletDialog onto the settings-modal reference design —
presentation-only, no change to the crypto/state-machine/secret-wipe logic:

- struct-form BeginOverlayDialog(OverlayDialogSpec{BlurFloat, cardWidth, idSuffix})
  replacing the legacy positional overload (same visual style, dp-scaled width)
- amber TextWrapped warning -> material::DialogWarningHeader(wiz_encrypt_warning)
- drop redundant Separator dividers
- every hardcoded English string -> TR() (13 new enc_*/change_pass_* keys added to
  the English source + all 8 res/lang/*.json additively; CJK subset rebuilt)

The strength-meter math, 3-phase transitions, "cannot close while encrypting"
guard, memset/SecureVault buffer wipes, and the encrypt/changePassphrase/vault
async paths are byte-for-byte unchanged. Verified: build + ctest + hygiene clean,
wiz_strength %s format-string safe across all languages, and a 3-lens adversarial
review (secret-hygiene / presentation-only / ui-i18n) returned zero findings.
