Export: ODS meta block + header-row freeze/filter; flat CSV with aligned column names.

Browse Source 
ODS sheets now carry a per-connection meta block (Connection / Transform
/ Left / Right) above the data; the header row anchors the freeze, the
auto-filter range, and the zebra striping. CSV stays a single flat
15-column table whose names match the ODS headers exactly.
