Convert all ASCII diagrams to mermaid with consistent styling
Replace ASCII art diagrams in 9 guide files with mermaid flowcharts
using a unified style system:
- 5 semantic colors (Okabe-Ito derived, color-blind safe):
teal (nodes), sky blue (instances), blue (network),
amber (load balancers), mauve (management)
- classDef for reusable styles, tinted subgraph fills
- Max 2 lines per node, specs in companion tables
- <br/> for line breaks (not \n, which Gitea renders literally)
- Solid arrows for data flow, dashed for control plane
Files converted:
- haproxy-guide.md (1 diagram)
- observability-guide.md (1 diagram)
- api-interception-guide.md (1 diagram)
- incusos-break-fix.md (3 diagrams: partitions, boot chain, updates)
- shared-storage-guide.md (3 diagrams: iSCSI arch, topology, multi-host)
- networking-guide.md (2 diagrams: bridge, OVN topology)
- operations-center-guide.md (1 diagram)
- ovn-deep-dive.md (3 diagrams: lab, bridges, Geneve mesh)
- production-lab-guide.md (1 diagram)
- mermaid-test.md updated as style reference with <br/> fix
