TOTP enrollment previously round-tripped the generated secret through a
hidden form field and saved whatever the client submitted, letting an
attacker with session access enroll a 2FA device they control by posting
their own secret plus a matching code. Stash the secret in the session
at GET /totp/new, read it only from the session at POST /totp, and drop
the hidden field from the view. Notify the user by email on successful
enrollment so unauthorized activations are visible even if a new vector
appears later.

The replay handler previously used a created_at time-range filter to
target access tokens and called update_all(expires_at:), which left
revoked_at nil, skipped refresh tokens entirely, and could miss or
falsely catch tokens from concurrent flows. Add an oidc_authorization_code
FK on both token tables, carry it through refresh-token rotation, and
use the association to revoke every descendant via revoke! (which sets
revoked_at and cascades access -> refresh).

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.

- Test ApplicationGroup cache busting on add and remove
- Test first failure persists in rate limit cache (increment fallback)
- Test bearer token failures count toward rate limit
- Test rd parameter rejected for deactivated applications
- Test last_activity_at updates after debounce window expires
- Test successful requests don't reset failure counter

- Remove duplicated app_allows_user_cached?/headers_for_user_cached methods; call model methods directly
- Fix sliding-window rate limit bug by using increment instead of write (avoids TTL reset)
- Use cached app lookup in validate_redirect_url instead of hitting DB on every unauthorized request
- Add cache busting to ApplicationGroup so group assignment changes invalidate the cache
- Eager-load user groups (includes(user: :groups)) to eliminate N+1 queries
- Replace pluck(:name) with map(&:name) to use already-loaded associations
- Remove hardcoded fallback domain, dead methods, and unnecessary comments
- Fix test indentation and make group-order assertions deterministic

Rate limit failed attempts (50/min per IP) with 429 + Retry-After.
Cache forward auth applications in a dedicated MemoryStore (8MB LRU)
to avoid loading all apps from SQLite on every request. Debounce
last_activity_at writes to at most once per minute per session.

Replace CGI.parse (removed in Ruby 4.0) with Rack::Utils.parse_query
in application controller, sessions controller, and OIDC tests.

Enables server-to-server authentication for forward auth applications
(e.g., video players accessing WebDAV) where browser cookies aren't
available. API keys use clk_ prefixed tokens stored as HMAC hashes.
Bearer token auth is checked before cookie auth in /api/verify.
Invalid tokens return 401 JSON (no redirect). Requests without
bearer tokens fall through to existing cookie flow unchanged.
