fix(import): add h2 columns with defaults for prod data missing 4 cols

The prod data export was made before http/2 columns were added to
http_logs (h2_fingerprint, h2_settings_fp, h2_window_update,
h2_pseudo_order). The INSERT SELECT now provides empty/zero literals
for those 4 columns so the 56-col Native export imports into the
60-col table without a column count mismatch.
