Render affiliations as separate paragraphs

[xchuam]

Summary

Update create_affiliations_blocks() to emit one pandoc.Para per affiliation instead of combining all affiliations into one paragraph separated by manual line breaks.

Motivation

In DOCX output, affiliations can inherit a justified paragraph style. When multiple affiliations are separated by manual line breaks within one paragraph, Microsoft Word stretches the spacing on every line except the last.

Using separate paragraphs prevents this unwanted justification and represents each affiliation as an independent block.

Validation

• Rendered example.qmd to DOCX with Quarto 1.9.38.
• Confirmed that each affiliation appears in a separate Word paragraph.
• Confirmed that no manual line breaks remain between affiliations.
• Confirmed that superscript numbering and affiliation text are preserved.

Note

Vertical spacing between affiliations follows the paragraph style in the reference DOCX and can therefore be customized through that document.
