QA follow-up on 5d45f5a8: that commit taught the converter to export heading
textAlign (<hN style>) but left the converter-gate heading test still asserting
the OLD dropped behavior (expects a bare '## text'), so jest was RED — the G1
green-suite gate was not actually met. Two gaps closed:
1. Flip the heading KNOWN-DIVERGENCE gate test to assert the round trip now
PRESERVES alignment (exported as <h2 style="text-align:center"> and recovered
on import), matching the shipped converter behavior. Suite is green again.
2. blockToHtml (the nested-container path: heading/paragraph inside a
column/table/callout) still emitted bare <hN>/<p>, dropping textAlign for
nested blocks. Carry the style there too, symmetric with the processNode path.
Also add #7 (table inside a column) and #8 (multi-block table cell) to the
lossless round-trip CORPUS so both survive export->import through the real
editor-ext schema (columns widthMode pre-authored at its normalize fixpoint).
Verified: server jest 193 suites / 2142 tests green, git-sync vitest 704 green,
no type errors.
