docs: fix Mermaid diagram \n sequences — use <br/> for line breaks

Mermaid renders literal \n in diagram labels as text. Replace with
<br/> throughout all sequence and flowchart diagrams. Also quote
flowchart node labels that use HTML entities, and collapse edge labels
that had embedded newlines to single-line text.
