fix(base): strip global ProseMirror 3rem horizontal padding from full-page base title

core.css globally pads .ProseMirror with 3rem on each side, so the
TitleEditor's content sat 48px further in than the table below. Add
a .base-page-title scope that resets the padding to 0 (only on the
full-page base title wrapper), so the outer 24px paddingInline is
the single source of horizontal positioning. Doc pages and the
embedded BaseTable are unaffected — neither uses the new class.
