perf(2meet-data-optimizer): drive flat-sorted searches from the flat table

Browse Source 
- A filtered search ordered by a flat column is rewritten to SELECT STRAIGHT_JOIN … FROM flat INNER JOIN wp_posts, with posts.ID tie-breaks (ours and plugin-appended) read as the equal flat post_id, so MariaDB sorts one table instead of looking every post up and sorting in a temporary table
- Only when the routed conditions already require a flat row on the sort group, without the copy route or a selective post filter; filter tmdo_router_flat_first turns it off; split_the_query compares with the same rewrite
- Verify: tests/live/run.php router (13/13); integration 522; dev36 page SQL Q07 263→147 ms, Q15 250→142 ms; fe.sh hourly_rate__desc 850→367 ms, ids == native
- PR: PR-062c
