Add GoogleMapsEmbed.tsx — consent-gated Maps embed, prepared but unused

Uses Klaro's own built-in contextual-consent mechanism (not
loadTrackingCode.ts's script-injection path) — the iframe renders
with data-name="google-maps" and its real src; Klaro's DOM scan finds
it after mount and blanks/restores src based on that service's
consent state, showing its own placeholder (styled via
KlaroConsentManager.tsx's KlaroTheme) in the meantime.

No map embedded anywhere in the app yet — this is prep work only, per
explicit request ahead of an actual page needing one.
