refactor(auth-ui): tighten LoginPage UX, a11y, and dead code

LoginPage cleanup:
- Drop dev pre-fill credentials and the secret logo-as-button trick
- Remove duplicate in-component theme toggle; accept isDark as a prop and let the (auth) layout's global theme toggle drive it
- Move passkey CTA below the password form so the primary flow stays primary
- Remove the dead "Angemeldet bleiben" checkbox (was bound but never forwarded to onSignIn)
- Fix the skip-to-form link to use sr-only/focus:not-sr-only so it only appears on keyboard focus
- Fix the "oder" divider to render its before/after hairlines by setting an explicit color on the parent
- Wire focus-visible outlines on all interactive controls
- Bump 0.6 → 0.75 opacity on subtitle text for AA contrast
- Drop opacity-60 from the headerControls wrapper

Robustness:
- Track all setTimeout IDs in a Set and clear them in an effect cleanup so navigation away doesn't fire stale callbacks (success redirects, error shake, focus restore)
- Replace (result as any) casts with the new typed AuthResult fields
- New resolveErrorCode() helper prefers result.errorCode and falls back to legacy string matching, so rate-limit / account-lock detection survives i18n
- WebAuthn Conditional UI: on mount, if PublicKeyCredential.isConditionalMediationAvailable(), call onSignInWithPasskey({ conditional: true }) so passkeys appear inline in the email autofill dropdown
- Extract the dismissible success-banner markup into a {#snippet successBanner} and reuse it for the verified / verification-sent / magic-link-sent cases (~50 lines of duplicate JSX out)

Page wrappers:
- login/+page.svelte passes isDark={theme.isDark} so the in-app theme store drives both layouts
- register/+page.svelte wraps trackGuestConversion() in queueMicrotask + try/catch so analytics can never block the success redirect
- Drop the dead baseSignupCredits={25} prop from register/+page.svelte (RegisterPage never accepted it)
