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.
