Wave 2: content fixes, deploy pipeline, layout refinements

- dorveille.md: add ai-model/ai-provider frontmatter, restore mark tags
- hugo.toml: goldmark.renderer.unsafe=true (mark/abbr support)
- layouts: extract nav partial, fix JSON-LD, simplify list/index
- deploy.sh: push-to-render build script (webhook-receiver triggers it)
- render-footnotes.html: class-free footnote hook (staged for Hugo upgrade)
