i18n: publish the bootcamp page in DE + ES, cluster the EN page, price 465.00

- add de|es/odoo-erp-automation-bootcamp/index.html (build-i18n.py from the
  translator's files; canonical + hreflang cluster + top-bar selector)
- EN bootcamp page gains the four hreflang alternates (was asymmetric)
- price 790 -> 465.00 across all three pages (JSON-LD offers.price, the three
  buy-button labels, the bc-price sentence); the three buy forms stay
  byte-identical apart from the label language
- sitemap.xml: +/de/ and /es/odoo-erp-automation-bootcamp/; llms.txt: Languages
  section names the new pages
