feat(2meet-data-optimizer): repair drifted flat rows from native with drift-check --fix

Browse Source 
- TMDO_Drift_Check::fix() deletes flat rows of deleted entities and, for post groups, of posts outside the group's post types; rebuilds every other drifted entity's row from native through the new TMDO_Entity_Migration_Engine::migrate_entity() (keys without native rows become NULL, PR-066); keeps a row whose entity has no native value for the group but clears its columns (no NULL-only inserts, no deleted rows the router may join on); invalidates the row cache of each touched entity; then checks again. Native meta is never written.
- `wp tmdo drift-check <entity> --fix` (not combinable with --sample).
- Verify: DriftCheckTest fix cases (RED: method missing); dev36 --fix: post 42 rows rebuilt, 1 stray row (post 312, hp_booking in hp_draft_flags) deleted, all four entities 0 drift after, checker miss/extra 0.
- PR: PR-071
