Replace ASCII-art diagrams across the README and docs/ with editable
.drawio sources plus exported PNGs, so the diagrams render clearly in
rendered markdown and can be maintained/regenerated instead of being
hand-edited as fragile text art. Non-diagram blocks (code, folder
trees, UI wireframes) were left as text.
Brainstorming output for a sibling docker-env2/ tree that brings up a
minimal second cluster (2 central + 1 site x 2 nodes + Traefik) on the
same machine alongside the primary docker/ stack. Shares the existing
scadalink-net network and scadalink-mssql container but uses separate
logical databases (ScadaLinkConfig2 / ScadaLinkMachineData2) so the
Transport (#24) feature can be exercised end-to-end with real
cross-environment exports and imports.
