* docx: keep a paragraph's text alignment w:textAlignment (ECMA-376 17.3.1.39) was not read, so a save dropped it. Word sizes a line by it when a list's bullet is larger than the text: without it, those lines grow and every page after them moves. ParaProps gains text_alignment, read and carried through styles, and written back after w:jc. Kept for the file only; the layout does not use it yet. * contributors: add entropybeater --------- Co-authored-by: Brian <255903314+entropybeater@users.noreply.github.com>
