fix: CI failures across Elixir, C#, Go, and musl builds

- Add PaddleOCR skip handling to C# and Go E2E generators
- Add missing AssertDocument, AssertOcrElements, SkipIfPaddleOcrUnavailable
  helpers to C# and Go test templates
- Fix Elixir doctest missing include_document_structure field
- Fix musl build __GNUC_PREREQ macro in tesseract wrapper
- Fix paddle_pdf_scanned.json path typo (pdfs/ -> pdf/)
- Revert getrandom to 0.3.4 for WASM compatibility
