fix(models): make API tokens work on /api/v2 routes
Sub-phase G validation caught that a token scoped to e.g. `labels.read_one` was rejected on /api/v2/labels because the route collector only stripped /api/v1/ from paths and did not know about v2's REST-style verbs (POST create, PUT/PATCH update, inverted from v1 where PUT creates and POST updates). Introduce a shadow apiTokenRoutesV2 map keyed under the same (group, permission) names as the v1 entries. Route collection now routes v2 paths into this shadow map and CanDoAPIRoute consults both tables, so the same permission bit authorizes the v1 and v2 endpoints for the same resource without changing the data shape served at /api/v1/routes (which the frontend token UI depends on). Also teach getRouteDetail about PATCH so Huma's AutoPatch-synthesized PATCH routes collapse to the `update` permission instead of being dropped.
