Fix the last 1,370 broken internal links, empty PT page and canonicals

Broken internal links: 1,370 -> 0 occurrences.
- 1,068 resolved context-aware: the same dead path needs a different destination on
  each locale, so resolution is per (page, target), not per string. Old-site routes
  (/contacto/, /servicios*, /consultoria*, /implementacion*, /recursos*) go to the
  page's own locale home or /odoo/ hub; legacy /odoo-ai/ paths are rewritten to
  /odoo-ia/; locale pages linking a root slug get their own locale's version.
- 301 remaining point at inline body links to pages that were planned but never
  written (35 locale hosting articles, 5 old /odoo-ai/ slugs, dead sections). Those
  fall back to the same-language section hub rather than 404.

Empty PT page: pt/odoo-ia/odoo-sistema-reservas-booking-ia-2025/ was 0 bytes and
returned an empty 200 from the PT sitemap. Removed it, its <url> block and every
hreflang alternate pointing at it; the 5 PT pages that linked to it now point at
/pt/odoo-ia/.

Canonicals: 23 relative -> absolute (a relative canonical carries no host, and apex
and www both answer 200). 62 pages had a second canonical added in the previous pass
because theirs was written href-first; duplicates removed, every page now has
exactly one. 404.html deliberately has none.

English homepage: title, description and H1 aligned to the 'odoo experts' query.
