Security-review follow-ups on the OIDC flows.
IPv6 loopback redirect_uri in dynamic client registration (RFC 8252):
- valid_redirect_uri? compared URI#host, which returns the bracketed "[::1]"
for IPv6 literals, so http://[::1]:PORT/... was always rejected. Compare
#hostname (unbracketed) instead, unblocking IPv6-only native clients.
Extract redirect_authorize_error (removes 12 copies of the boilerplate):
- The authorize/consent flows built the error redirect by hand ~a dozen times
(error_uri = "...?error=..."; += "&error_description=#{CGI.escape ...}"; +=
state; redirect_to). One helper now composes the query, and — unlike every
copy — appends "&error=..." when the redirect_uri already has a query string
instead of a malformed second "?".
Extract token-endpoint helpers (removes ~80 duplicated lines):
- authenticate_token_client: the identical client-auth preamble shared by the
authorization-code, refresh, and device-code grants.
- render_token_triple: the access + refresh + id_token mint and RFC 6749 §5.1
response shared by the authorization-code and device-code grants.
Single source of truth for scope descriptions:
- New OidcHelper#scope_description + shared shared/_scope_list partial, used by
both the browser consent screen and the device authorization screen; drops the
scope_labels hash and the hard-coded per-scope blocks that would have drifted.

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.

When an application has no icon attached, render a deterministic
monogram SVG instead of the generic picture-frame placeholder. Initials
are picked from capital letters in the name (ShelfLife -> SL); fall
back to the first two letters when fewer than two capitals exist
(Audiobookshelf -> AU). Background colour is hashed from the name for
stable per-app identity across visits.
Adds an optional second icon attachment, icon_dark, alongside the main
icon. When present, render a <picture> with a prefers-color-scheme:
dark source so the browser swaps automatically; when absent, the main
icon is used in both modes. The SVG sanitization, content-type fix,
and size/format validation now run over both attachments uniformly.
Bumps to 0.14.0.

Uses Tailwind v4 class-based dark mode with a Stimulus controller for
toggling. Respects prefers-color-scheme as default, prevents FOUC with
an inline script, and persists the user's choice in localStorage. All
views updated with dark: variants for backgrounds, text, borders,
badges, buttons, and form inputs.
