Added Structured Data and Noindex Controls Across Basker

Each theme used to solve the same structured-data and noindex rules on its own, with inconsistent results. Basker now centralises structured data generation across render modes and respects noindex settings consistently, so search engines and social platforms see accurate metadata for every page.

Canonical URLs

Canonical URLs now resolve against each site's primary domain, giving teams better default SEO for event pages, series, venues, and reusable content.

Reliable noindex behaviour

A page marked as noindex in the CMS now reliably stays out of search. There is no longer a theme-specific override required to make that instruction stick.
