v1.1.0: headerless mode for audits printed without row/column headings

Sniffs the format on page 1: printed row numbers -> gridded mode
(unchanged); UUID-keyed rows -> new headerless mode, which anchors rows
on per-record UUIDs and takes the column map from the page-1 header
labels. Handles fused cells (ID+Name+Org+networks), mid-value line
wraps, two-timestamp Time Frame ranges, wrapped header labels, and
per-export schema drift. Validated against three monthly JC PD audits:
120/120 cross-engine spot checks, 0 anomalies, field-identical to the
standalone converter it replaces.
