feat(setup-wizard): improve E2EE dialog UX and password field

- Only show the passphrase and "Obfuscate Properties" controls once
  end-to-end encryption is enabled, instead of leaving them visible
  but disabled.
- Replace the password show/hide checkbox with an icon toggle button.
- Let translated labels wrap to their content instead of being
  clipped into a fixed-width column (this clipped longer translated
  labels, e.g. in German and Spanish).
- Scope the onboarding invitation link's 44px touch-target padding to
  mobile, so on desktop it renders as a normal inline link instead of
  a stray, oddly-padded button.
