Summary

Content refresh of docs/operations/troubleshooting/index.md: added a diagram, fixed grammar/typos, and tightened phrasing throughout.

Added a diagram showing the reconciliation dependency order (Iron Bank Authentication → Flux Install → Git Repository → Kustomization → ConfigMap/Secrets & Helm Release → Packages), styled consistently with the color scheme and shapes used on the Renovate pages.
Fixed grammar and typos: "timed and pods" → "timed out," two instances of "abut" → "about," "occurs to early" → "occurs too early," and a garbled duplicate "in" in the Kustomization table ("resource in is incorrect" → "resource is incorrect").
Tightened the two opening paragraphs, which each separately stated the same point twice.
