Document publicationFilter for REST, GraphQL, and Document Service API

[innerdvations]

Summary

• Add dedicated publicationFilter reference pages for the REST API and Document Service API, with GraphQL documented as a new section on the GraphQL page.
• Document cohort values, status × publicationFilter behavior, default-status differences across API surfaces, Content Manager mapping, validation, and deprecated hasPublishedVersion.
• Cross-link from status, parameters, document-service method tables, and Draft & Publish; update sidebar navigation and regenerate LLM artifacts.

Test plan

• yarn generate-llms and yarn llms:generate-and-validate pass
• yarn build in docusaurus/
• Spot-check sidebar order: REST → Parameters → … → Status → Publication filter → Populate & Select
• Verify links from Draft & Publish feature page to new API docs

@pwizla This is one from a few months ago that we wanted a soft launch on to make sure it was stable, but is fine to publicize now. It looks like my AI went a bit overboard on detailing this, so feel free to trim it down or just pull out the relevant details/examples and replace it

[innerdvations]

Also, we may want to remove the reference to hasPublishedVersion -- as far as I know it was never officially documented, so we probably don't want to even include it here at all, it seems weird to add it to docs already deprecated. What do you think?

[pwizla]

Thanks for the contribution, Ben! I'll review this tomorrow.
Would you please have a base strapi/strapi PR or branch I can relate to? (I do remember the hasPublishedVersion topic, PR #2966 , but would like to know which branch my code exploring agents should look at 👀 )

It was added in strapi/strapi#25793 with a follow-up fix in strapi/strapi#26400 (although that one you can probably leave out)

Thank you, Ben. I've just updated the PR description with these. I'll actually move the review to next Monday, to focus on some other work today. Will keep you posted!
