test(no-invalid-interactive): promote peer-parity cases, drop audit file

Promoted valid DIVERGENCES: a[tabindex=0] without href (tabindex makes it
interactive; jsx-a11y flags it), and non-disallowed handlers (onmouseenter,
onmouseleave, oncontextmenu, ondrag — not in DISALLOWED_DOM_EVENTS, aligns
with jsx-a11y recommended). Promoted invalid DIVERGENCES: section with
aria-label (aria-label does not affect our interactivity check), menuitem and
datalist (not in NATIVE_INTERACTIVE_ELEMENTS unlike jsx-a11y), and
input[type=hidden] (explicitly excluded from native-interactive).
