Without Remember-me the session cookie was still being written via
`cookies.signed.permanent`, so it survived browser restart on shared
devices — surprising for a user who explicitly opted out of Remember-me.
Issue a browser-session cookie (no Expires) when remember_me is off;
the server-side Session#expires_at still bounds the 24h / 30d window.

An observed fa_token (via Referer leaks, access logs, JS monitors)
could previously be redeemed against a different reverse-proxied app
within the 60s TTL. The token now stores the destination host at
creation and the verifier rejects mismatches without burning the cache
entry, so legitimate destinations can still redeem.

- Add "Remember me for 30 days" checkbox (30-day vs 24-hour session expiry)
- Center heading and constrain form width to max-w-md
- Preserve remember_me preference through TOTP and WebAuthn auth flows

Remove PKCE plain method support (S256 only), enforce openid scope requirement,
filter to supported scopes, strip reserved claims from custom claims as
defense-in-depth, sanitize SVG icons with Loofah, add global input padding,
switch session cookies to SameSite=Lax, use Session.active scope, and remove
unsafe-eval from CSP.
