Bug: Entitylist preload expansion ignores continuation tokens and requests whole list at once

Problem: _extract_entitylist_payload returns only payload[0] and throws away payload[1], which is the continuation token. _expand_entitylist_preload_text then rewrites the page-size parameter to total_rows and makes a single enormous request. If Google rejects that size, the except Exception: return None silently keeps the truncated first payload.

Evidence:

candidate = payload[0]          # payload[1] (continuation token) is ignored

Suggested fix: Parse and use the continuation token. Implement a paginated fetch loop:

1. Fetch the preload.
2. If len(rows) < total, use the token from payload[1] to request the next page.
3. Accumulate rows (or the full payloads) into script_texts.
4. Cap the single-request page size and log a quality flag when pagination is used.

Difficulty: high-value
Impact: High — saved lists with many places may be truncated or silently incomplete.
