sadpandajoe 0270e32719 fix(plugin-chart-table): match scrollbar styling on sticky header/footer ...

scrollbar-gutter: stable's reserved width depends on whether custom
::-webkit-scrollbar styling is applied to that element (verified in both
headless and headed Chromium: 15px unstyled vs 8px styled, matching
CUSTOM_SCROLLBAR_SIZE). The previous fix reserved the gutter on the
header/footer wrappers without also giving them the same custom scrollbar
CSS the body/sizer carry, so they reserved a different (larger) amount and
could still clip the shared colgroup's rightmost column.

Also corrects the RCA: real, non-headless browser testing shows unmodified
master's original scrollBarSize-based computation does not diverge from
the body/sizer's reservation under any real condition reproduced in this
investigation (only headless Chromium's synthetic scrollbar probe showed a
difference, which turned out to be a headless-only rendering artifact, not
representative of a real user's browser). The fix still removes a real,
demonstrated defect class -- relying on two independently-measured
scrollbar-space numbers to agree -- rather than the exact historical
trigger, which remains unpinned.
