v1.2.0

This is a minor release focused mainly on improving performance to mitigate against the large volume of traffic we are receiving from bots and crawlers (#411).

It also includes a new "functional classifications" entity and related APIs. This is a new approach to categorising the type of occupation(s) at a site.

New features & API changes:

• Added unique and "one blank per site" constraints on context names (#432)
• Added functional classifications of contexts (#407)
  • Added curation workflow for functional classifications of contexts
  • Added issue view for contexts missing functional classifications
  • Added functional classification suggestions based on site type labels
  • Added JSON builder for functional classification data
• New admin dashboard for monitoring asynchronous jobs (/admin/jobs)
• Improved workflows for record deletion
  • Unused references, taxons, and materials are now automatically deleted
    • Added rake tasks to cleanup unused
  • Ensured dependent records are properly cleaned up after site deletion
    • Added rake task for safe cascading destruction
  • Prevented duplicate citations from being created
    • Migration may fail if there are existing duplicates in the database. If so:
      DRY_RUN=1 bin/rails xronos:citations:deduplicate
      checks for existing duplicates that would block this migration. And:
      bin/rails xronos:citations:deduplicate
      deletes them.
• Added bundled acknowledgements page rendered from version-controlled Markdown (#359).
• Added article-specific page titles and meta descriptions for news, about, and documentation articles.

Bug fixes:

• Sign-in cookie is now deleted on sign out (#379)
• Fixed Leaflet marker initialisation on site pages with quotation marks or apostrophes in site names.
• Fixed data browser map display for records with missing coordinates.
• Added countish pagination for large public listings to reduce expensive repeated count queries.
• Fixed potential code injection vulnerability in issues (#407)

Maintenance & documentation:

• Standardised the test suite on Minitest and migrated existing RSpec coverage (#422).
• Documented expectations for responsible API and automated data access (#405).
• Updated footer logos to reflect current affiliations, funding, and previous support (#404).
• Upgraded Rails from 7.2.3 to 8.0.5 and enabled Rails 8.0 framework defaults.
• Upgraded Pagy from 6.5.0 to 43.5.5 and migrated pagination helpers to the Pagy 43 API.
• XRONOS rake tasks are now prepended with xronos and can be listed with
  bin/rails -T xronos
