Fix tbl-column: margin for Typst output (closes #13929)

Apply scoped column classes (fig-column, tbl-column) directly to
FloatRefTargets in columns-preprocess.lua, bypassing the Div propagation
chain which silently failed for tables. Also fix copy-paste bug in
base.ts where fig-caption- prefix was used instead of fig-column-/
tbl-column-.
