Daniel 8f49c4dcb9 feat(mobile): biometric sign-in (Face ID / Touch ID / fingerprint)
Adds opt-in biometric login to the Capacitor app. Replaces the password
step on subsequent sign-ins; the 2FA step (if any) still applies — by
design, defense in depth.

How it works:
- After a successful password sign-in on a Capacitor build, prompt the
  user to enroll. If they accept, capacitor-native-biometric.setCredentials
  stores the (email, password) pair in the iOS Keychain / Android Keystore
  with biometric-protected access. The local flag ped_bio_enabled=1 is
  set so the next launch knows to probe.
- On the login form, if isNativeApp() + bioStored() + bioAvailable.ok,
  reveal the "Sign in with Face ID / Touch ID / fingerprint" button at
  the top. Label is set from the actual biometryType returned by the
  plugin so users see what their device supports.
- Tap → verifyIdentity (OS prompt) → getCredentials → fill the email +
  password fields → fire the existing form submit so all the regular
  flow runs (turnstile, 2FA prompt, error handling, session storage).
- Explicit logout deletes credentials AND clears the local flag,
  hiding the button on the next visit. Auto-logout (token expiry,
  network) does NOT come through that path, so biometric persists
  across silent session resets.

Storage choice — password not JWT:
- JWTs expire and the storage would constantly need refresh.
- Storing the password lets the standard /api/auth/login flow run,
  which already handles password-rotation (a stale stored password
  just fails 401 → user falls back to typing the new one → re-enrolls).
- The password sits in OS-level secure storage, accessible only after
  successful biometric verification — same security posture as a
  password manager autofill.

Files:
- mobile/package.json: add capacitor-native-biometric@^5.0.0 (Capacitor 6
  compat)
- mobile/android/app/src/main/AndroidManifest.xml: add USE_BIOMETRIC
  uses-permission
- mobile/ios/App/App/Info.plist: add NSFaceIDUsageDescription string
- public/js/auth.js: bioPlugin/bioAvailable/bioStored/bioEnroll/
  bioRetrieve/bioForget helpers; window.PedBio surface; reveal-on-load;
  click handler; post-login enrollment prompt; logout cleanup
- public/index.html: hidden #btn-bio-login + #bio-divider above the
  email field on the login form
- public/css/styles.css: themed gradient button + hover lift
- mobile/README.md: feature list updated

Build steps for Daniel:
  cd mobile && npm install        # picks up capacitor-native-biometric
  npx cap sync                    # ports the plugin into android/ + ios/
  # then build APK / IPA as usual
