feat(freelancer-directory): go live — indexable, sitemap + llms, og:image, Plausible, homepage inbound link

- /odoo-community-developers/ no longer noindex,nofollow; title/description/H1 target 'hire odoo developer'
- added og:image + og:image:alt (the page's own hero), twitter summary_large_image
- Plausible snippet copied byte-for-byte as the last thing in <head>
- sitemap.xml + llms.txt entries
- one inbound link: a homepage FAQ card (client-facing, the established FAQ->page pattern)
- relay forms untouched: ODOO_EXPERTS_QUOTE_WEBHOOK / ODOO_EXPERTS_INVITE_WEBHOOK stay empty
- admin page (/admin/) stays noindex and unlinked
