feat: vitrine language/theme switching, missing features, disabled-signups handling

Language switcher (flag toggle) and dark-mode toggle in the marketing header, both usable by logged-out visitors -- the marketing pages previously hardcoded English (getMessages(undefined)) regardless of any preference, and had no theme control since the authenticated Nav's toggle isn't rendered there. New cookie-based locale resolution (lib/marketing-locale.ts) separate from the authenticated app's useLocale/setLocale, which persists via an authenticated PATCH that would just 401 and revert for an anonymous visitor. Root layout now falls back to that cookie for <html lang> when there's no session. Features/Home now cover cook mode, recipe variations, personalized recommendations, and ingredient substitution -- all real, shipped features that were missing from the page copy. Signup CTAs check isSignupsDisabled() and swap to "Signups closed" instead of "Get started free" -- still linking to /signup, since that page already handles the invite-token exception correctly. Fixed along the way: importing the cookie-name constant from marketing-locale.ts in the client-side LanguageSwitcher pulled that file's server-only imports (lib/auth/server -> the DB client -> `postgres`) into the client bundle, breaking the build on Node built-ins. Split the constant into its own client-safe file (marketing-locale-cookie.ts). Caught by `pnpm build`, not typecheck. Verified with typecheck, lint, and a full production build (clean compile) -- no DB in this sandbox to click through a real dev server. v0.48.1
