fix(2meet-data-optimizer): join each routed group and drop the redundant GROUP BY

Browse Source 
- posts_join joins the flat table of every routed group (a wp_core key next to a post type group no longer fails with "Unknown column")
- Flat tables are one row per post (UNIQUE post_id): remove the posts_groupby hook; skip the INNER JOIN status/date copy route for NOT EXISTS, which must match posts without a flat row
- Verify: tests/live/run.php router (9/9); qbench Q05 475 == native, no SQL error; price filter EXPLAIN has no Using temporary
- PR: PR-061
