0.8.3

Added

• A documentation site, https://dim145.github.io/arr-metadata-server/, built
  with Starlight from docs/ and the README and published on GitHub Pages by
  .github/workflows/docs.yml. Each page is written once and stays readable
  on GitHub: the build rewrites the links between pages and stops on one that
  leads nowhere.
• docs/settings.md: every setting — what it holds, its default, where it
  may be set, the variable that seeds it — written from the settings registry
  by UPDATE_DOCS=1 cargo test settings_reference; cargo test fails when
  the page and the code disagree. docs/reverse-proxy.md: nginx, Traefik and
  Caddy in front of the server — AMS_PUBLIC_URL, AMS_TRUSTED_PROXIES, the
  headers read, the paths to keep off the internet.

Changed

• The OpenAPI document (/api/openapi.json) describes what the server sends.
  Ten schema names stood for two types or more — Role, Status, Counts,
  Mode, Entry, Kind, Source, and Radarr's RatingResource,
  ImageResource and AlternativeTitleResource, which carried Skyhook's
  shape — so twenty-five fields were documented with another type's shape:
  each type has its own name now (AccountRole and PersonRole,
  AccountStatus, SkyhookRatingResource…). Every operation has an id of its
  own, <module>_<handler> (users_list), where fifty-three shared sixteen;
  and the sixty-seven fields the native API always sends, null when empty,
  are listed as required. Nothing the server sends has changed; a client
  generated from the document gets the new names. cargo test fails when two
  types share a name, when an operation lacks its id or shares one, or when a
  field always sent is documented as optional; the interface's generated
  types are a .ts the compiler checks.
• The README is down to what the server is, what it serves, a quick start
  and the first steps for Sonarr, Radarr and Plex. The rest moved, unchanged
  in substance, to new pages under docs/: installing, configuration (every
  environment variable), sources, languages, media, caching, several
  instances, accounts and access, security, the API.
• The interface loads only the language it is read in: English and French
  are separate files, the reader's fetched before the first paint and the
  other only when chosen. The first download is a third lighter: 489 kB
  instead of 746 (148 kB compressed instead of 235).
• An API's access policy reads the same, in the same colour, on the
  dashboard, the configuration page and the access page; the public bar's
  language switch takes the administration's segmented look.
• Internal, with nothing to see from outside: the interface's types are
  generated from the server's own OpenAPI document (frontend/openapi.json,
  kept current by cargo test, UPDATE_OPENAPI=1 rewriting it, and turned
  into types by npm run types), and CI lints the interface (ESLint with
  typescript-eslint, react-hooks and jsx-a11y), runs its unit tests (Vitest)
  and fails when the generated types fall behind. The works' repository, one
  file of some five thousand lines, is six, each with its tests; the native
  API's handlers guard with Identity::require_admin and a new
  Identity::require_write instead of ten private copies of either.

Fixed

• A film's releases in a country listed those with no date first, and an
  undated rating could stand for the country instead of the dated cinema
  release's.
• A field locked to an object shows its JSON in the editor, not
  [object Object].
