Removed markdownToMobiledoc test helper

[sagzy]

ref https://linear.app/ghost/issue/GVA-816

Follow-up to #28906, which removed mobiledoc rendering and HTML-to-mobiledoc conversion. Test fixtures were still seeding post content as mobiledoc via the markdownToMobiledoc helper — since the model now converts any mobiledoc input to lexical on save, that content ended up stored as lexical anyway, so the helper was just a roundabout way of producing lexical content.

Changes

• Replaced DataGenerator.markdownToMobiledoc with DataGenerator.markdownToLexical, which produces the exact markdown-card lexical doc that mobiledocToLexical() emitted for these fixtures — stored content and rendered HTML are unchanged, so no snapshot updates are needed.
• DataGenerator.forKnex.createPost now defaults to lexical content (still accepts an explicit mobiledoc override), and DataGenerator.forModel.posts picks lexical instead of mobiledoc.
• Tests that deliberately exercise the legacy mobiledoc input path now build their mobiledoc locally, making the legacy intent explicit:
  • importer v1 tests (v1 exports predate lexical)
  • the force_rerender mobiledoc→lexical conversion test in posts-legacy.test.js
• The post-with-all-media-types-mobiledoc fixture and restoreLegacyMobiledocPosts are untouched — they still cover the legacy mobiledoc read/render paths.

Testing

• test:unit, test:integration, test:e2e and test:legacy run locally; every changed file passes in isolation (123/123 across the changed e2e files, 76/76 model-posts, 42/42 importer)
• Remaining local full-suite failures were verified to be pre-existing on the parent commit (hook timeouts / flaky members & trackDb tests reproduce identically on baseline)

Walkthrough

This PR updates test fixtures and helper utilities to use Lexical content instead of Mobiledoc across admin, content, frontend, webhook, importer, model, and unit test coverage. The shared fixture generator adds markdownToLexical, updates fixture post data and createPost HTML derivation, and returns lexical content in model projections. Most affected tests now send or expect lexical fields, while the importer v1 suite keeps explicit Mobiledoc coverage for legacy conversion paths.

Changes

• Fixture helpers and generators now produce Lexical content and default new posts to lexical.
• Many e2e and unit tests switch post/page fixtures from mobiledoc to lexical.
• The importer v1 tests retain Mobiledoc-specific inputs for legacy conversion assertions.
• Post model, scheduling, mapper, and frontend helper tests are aligned to Lexical fixtures.
