Add six 2027 country pages, built on verified localisation facts

New: /odoo/odoo-{bolivia,honduras,guatemala,chile,mexico,paraguay}-implementacion-local-2027/

Not templated filler. Each page answers what actually differs in that country:
- l10n module verified in the Odoo 19 community addons tree: l10n_bo, l10n_hn,
  l10n_gt, l10n_cl, l10n_mx exist; l10n_py does NOT (404). Paraguay's page is
  therefore about the absence of an official localisation and what that costs
  in maintenance, not a copy of the others.
- No l10n_*_edi module exists in the community tree at all, so every page states
  that e-invoicing is Enterprise or third-party — the cost most budgets miss.
- Partner links go to the official Odoo directory filtered by country (verified
  200): bolivia-28, honduras-94, guatemala-88, chile-44, mexico-150,
  paraguay-179. No individual firms are named: partner status changes, and an
  unverified endorsement is the same defect as the testimonials we removed.
- One affiliate CTA per page (utm_campaign=country-2027), disclosed.
- Article + FAQPage + BreadcrumbList schema per page.

Wired in: 2025 pages link forward to their 2027 counterpart (5 of them; Paraguay
has no 2025 page and says so), /odoo/ hub links all six, sitemap-es.xml +6 URLs.
Countries chosen by actual GSC demand: odoo bolivia 88 impr/3 clicks, odoo
honduras 86, guatemala 51 across three queries, then chile/mexico/paraguay.
