fix(frontend): narrow legacy cell alignment to Ref's markup

Ref never aligns `.tb_layout` cells from the table; each legacy cell opts in
with align=center. The directory title table, npc list and chief reservation
rows follow that, the nation info cells use Ref's gray rule, and the main
document stops clipping horizontally.
