docs(readme): add a screenshot of the Meet application itself, before the embedded one

The README only showed Meet embedded in a host application, which is the
second story. It now leads with the product as deployed — a real two-person
meeting captured from a local 3.8.0 deployment — and says plainly that using
it requires no code and that it is brandable. The embedded screenshot follows,
with the iframe and web-component route stated explicitly.

The new image is committed to the repo (docs/images/, 88 KB at 1120x630)
rather than hotlinked, because no standalone Meet screenshot is published on
openvidu.io: the site demonstrates the app with video, and its only stills are
the three embedded use-case shots.
