Move 14 identical style slots (text/heading/div/inline/link/small/bold/
richParagraph/richListItemRow/richListItemMarker/richListItemContent/
splitRow/alignEnd/picture) from all 15 template Page.tsx files into a
single createBaseTemplateStyles factory in templates/shared. Each template
now spreads …base and keeps only its real overrides. Resolved StyleSheet
values are identical to before. Update rtl-fixture and rich-text-template-
styles tests to guard the factory file rather than each template directly.
