docs: convert standard diagrams from draw.io PNGs to inline Mermaid

Gitea renders mermaid inline, so the flow/state/hierarchy/DAG diagrams move to text-in-markdown: auto-layout (removes the manual overlap-prone draw.io step), diffable source, no committed binaries, and a dark-text theme so labels stay legible. Keep draw.io PNGs only for the two complex bespoke diagrams (logical architecture, env2 topology) where pixel control still wins. All 24 mermaid blocks validated by rendering.

 T10 is the only task that requires all of T0–T9 done. Everything else can run in parallel.
