Update every element carrying the given data-field attribute,
scoped to container. A field key may appear more than once (the
Cache tab renders each value both in the full metric card AND in the
collapsed-header compact summary) — all copies get the same text.
Returns false if no matching element was found (the caller can use
the boolean to decide whether the DOM structure needs a full
rebuild).
