Fix the hardcoded LOCALE_ID: 'nl' — provide it from $localize.locale (the build-time
locale, 'nl'/'en', undefined→'nl' in dev) and register both nl+en locale data, so the en
bundle formats dates/numbers correctly. Make `docker compose up` serve the LOCALIZED build:
the web service now runs `ng build --localize` then serve-i18n.mjs, which gained a PORT env
+ an /api reverse-proxy (API_PROXY_TARGET → the api container) so both /nl/ and /en/ are
served with the language switcher working end-to-end. Drop the now-unused proxy.conf.docker.json
(serve-i18n proxies /api itself); update ARCHITECTURE. `npm start` stays the nl-only HMR loop.

Add a language switcher matching the CIBG Taal-instellen pattern: a <nav> region
(sr-only heading + aria-label) with an endonym link per locale (lang/hreflang, the
active one aria-current + non-link), mounted right after the skip link in the shell.
Compile-time $localize means each locale is its own bundle under /<locale>/, so the
switch is a full navigation to the sibling bundle — active locale read from the baked
base href. Pure localeLinks() (+spec) builds path-preserving targets. Since `ng serve`
serves nl-only at /, add `npm run serve:i18n` (localized build + a tiny static server
with per-locale SPA fallback) so the switch is demoable. +story.
