verify_totp called ROTP without `after:`, so a captured 6-digit code stayed
valid for the full ~90s drift window and could be replayed in a separate
sign-in. Add a last_otp_at column, pass it as ROTP's `after:`, and persist the
matched timestep on success so a code (or any earlier one) cannot be reused.
Also fixes a latent bug surfaced by the new replay path: enable_totp! did
`self.backup_codes = generate_backup_codes`, reassigning backup_codes to the
plaintext return value (generate_backup_codes already stores the BCrypt hashes
internally). That stored backup codes in plaintext and broke verification.
enable_totp! is test-only today, but it is public and backup_codes is not
encrypted, so this is a real footgun. Now it just calls generate_backup_codes.
Rewrites the mislabeled "TOTP code cannot be reused" test to actually assert
that replaying an accepted code is rejected.

The ApiKey model only validates group access on creation (user_must_have_access
runs on create). The bearer path in /api/verify never re-checked, so a user
removed from an application's allowed groups kept access via an existing key
until it was manually revoked.
Add an app.user_allowed?(user) check to authenticate_bearer_token, matching the
session path, returning 401 when the user no longer has group access. Adds a
regression test that revokes membership after key creation.

Two HIGH-severity findings from the security review:
- ForwardAuth: when no host header was present, /api/verify skipped the
application lookup and group check entirely, returning 200 with identity
headers (including all of the user's groups). This bypassed per-domain
access control. Now fails closed with 403, and the unreachable
DEFAULT_HEADERS fallback (the bypass path) is removed so headers are
always scoped to a resolved, active application.
- OIDC: the consent endpoint was in the verify_authenticity_token skip
list, so a forged cross-site POST could silently grant OAuth scopes.
Removed :consent from the skip list (the form already embeds the token).
Adds regression tests for both: fail-closed with no identity headers when
host is absent, and 422 on a tokenless consent POST.

The Applications index used to render "All users" whenever an app had
no allowed_groups; under default-deny that's the opposite of the truth.
Replaced with a "No one" badge and, when groups are present, a
"N users · M groups" cell so the access reality is visible at a glance.
Added a small stats strip above the apps table: applications, users
with access, and groups granting access. Backed by preloaded counts in
the controller to avoid N+1.
Added /admin/access — a small "Access check" tool that takes a user
and an application and reports whether the user can reach it, with the
granting group(s) when allowed, and the specific reason when not
(inactive app/user, no allowed groups, or no shared group). Wired into
the admin sidebar.

Replaces the implicit "empty allowed_groups means public" rule with
explicit default-deny across both OIDC and ForwardAuth. Adds two boolean
flags on Group — auto_assign (Keycloak-style auto-join on user create)
and admin (members can reach the admin panel) — and drops the
users.admin column entirely. Adds "Users with access" and "Accessible
applications" panels with via-group badges on the application/user show
pages.
BEHAVIOR CHANGE: a ForwardAuth app with no allowed_groups previously
bypassed authentication entirely; it now returns 403 like any other
unauthorized request. The data migration seeds an "everyone" group and
attaches it to all previously group-less apps to preserve behavior on
existing installs. An "admins" group is seeded and backfilled from any
user with the old admin column.

Adds an "Assigned Applications" checkbox list to the group new/edit
form so admins can grant a group access to multiple apps from one
screen, instead of editing each application individually.

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.

The refute_match on response.location already proves create_forward_auth_token
did nothing: the cache.write and the URL rewrite are back-to-back with no
branch between them, so the URL lacking fa_token= implies no cache entry
was written. The instance_variable_get(:@data) inspection was both redundant
and coupled to MemoryStore's private layout.

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.

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.

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.
