engineering: link audit cleanup

- Replace dead Wiley URL for Burton 2011 with e-bookshelf preview PDF
- Fix IEC 61400-12-1 landing URL (/en/publication/68499)
- Replace broken NREL Jonkman URL with stable OSTI biblio (www.osti.gov/biblio/947422); update jonkman_2009.bib url field
- Remove dead ENGIE original-portal URL; keep hostname annotation only
- Remove all historical '> note:' correction blocks (Karin, Lydia, Sohoni, Kragh & Hansen) for cleaner Links.md format
