Adds a `GATEWAY_PUBLIC_HTTP_CORS_ALLOWED_ORIGINS` env-driven allow-list
on the public REST server so the dev UI on https://www.galaxy.lan can
call https://api.galaxy.lan without the browser blocking the
cross-origin response. Defaults to empty (no CORS) so the production
posture stays closed.
The middleware mounts before route classification and anti-abuse, so
OPTIONS preflights never charge against per-class rate-limit buckets.
`tools/dev-deploy/docker-compose.yml` opts the dev gateway into a
single allowed origin (`https://www.galaxy.lan`); local-dev keeps the
defaults because Vite proxies through the same origin.

Adds a minimal Svelte 5 i18n primitive (`src/lib/i18n/`) backing the
login form, the layout blocker page, and the lobby placeholder.
SUPPORTED_LOCALES drives both the picker and the runtime lookup;
adding a language is a two-step change inside `src/lib/i18n/`.
Login form gains a globe-icon language dropdown (English / Русский
in their native names), defaulting to navigator.languages with `en`
as the fallback. Switching the locale re-renders the form in place;
on submit, the locale rides in the JSON body of `send-email-code`
because Safari/WebKit silently drops JS-set Accept-Language. Gateway
gains a body `locale` field that takes priority over the request
header for preferred-language resolution.
Email and code inputs disable browser autofill / suggestions
(`autocomplete=off` + `autocorrect=off` + `autocapitalize=off` +
`spellcheck=false`) so Keychain / address-book pickers and
remembered-value dropdowns no longer fire on focus.
Cross-cuts:
- backend & gateway openapi: clarify that body `locale` is honored.
- docs/FUNCTIONAL{,_ru}.md §1.2: document body-vs-header priority.
- gateway tests: body `locale` overrides Accept-Language; blank
body `locale` falls back to header.
- new ui/docs/i18n.md; cross-links from auth-flow.md and ui/README.
