chore(clean): dedup CV/index CSS, drop dead directives (tour F1-F8)

CV: shared block for xp/project/edu headers + date chips + roles + tags,
2 identical inline style attrs -> .inline-link class, no-op body margin/
padding removed, stray blank collapsed. Proven behavior-preserving: PDF
text-hash + per-page render-hash + full byte-identity vs committed PDF.
index: .stack-note/.theme-list code grouped, 2 no-op .formation overrides
removed. nginx.conf: dead 'deny all' after return 404 removed (nginx -t +
dotfile-404 oracle PASS). .dockerignore: phantom nginx.conf.bak entry.
Snippet comment: CV style attrs no longer exist. CSP hash unchanged.
