fix(2meet-data-optimizer): route post entity keys by post_type

- Entity groups can declare post_types; get_field() resolves a post's key against its own type's groups first, then unscoped ones (legacy last-wins lookup kept for callers without a post type)
- Hook Bus and the post query router pass the post type, so a listing's hp_rating / hp_status / hp_verified map to hp_listing_core instead of the vendor/request tables; core HP groups declare their post types (schema hashes unchanged)
- Behind tmdo_post_scoped_routing: on for sites without post flat rows, off where rows may sit in the wrong table until PR-034 reconciles them (dry-run: dev20–22 off, dev23/24/30/31/40 on)
- Verify: EntityRegistryScopeTest (8), PostScopedRoutingTest (4); core unit 630 / integration 443, HP 144/49, WC 10/22 OK
- PR: PR-033
