Sidebar referenced non-existent paths (modules/bmm/, getting-started/, etc.)
while actual docs live in different locations (modules/bmm-bmad-method/,
bmad-core-concepts/, etc.). Updated sidebar to match reality so Docusaurus
can build successfully.
Also fixed broken image reference in workflows-guide.md that used an
incorrect relative path.
