chore(docs): consolidate 22 audit files from root into docs/audits/

Root directory had accumulated audit/exploration markdown files cluttering
the project root. Moved all audit-related files to docs/audits/ with a
README.md index, and updated cross-references in K6_LOAD_TESTING_GUIDE.md
and README_FRONTEND_DOCS.md.
