fix(text): paragraph_gap ignored in non-scrollable render path

All blocks were given is_last=true via a shared NodeRenderOptions,
causing every block's margin-bottom to resolve to rems(0). Paragraph
spacing set via TextViewStyle::paragraph_gap had no visible effect.

Mirror the virtualized-list path: compute is_last per block so only
the final block gets zero bottom spacing.
