docs(reflow): replace architecture ASCII diagrams with prose and lists

- System Components: convert the box-and-arrow diagram to a short prose summary naming the three API endpoint groups and the three infrastructure dependencies. - How a document moves through the system: convert the tree-style flow to a numbered list with a nested branch under the PII scan step. Hub's markdown renderer has no Mermaid support, so plain markdown is the right level for these. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
