fix(types): register OrganizerLayoutV2/PortalLayoutV2 in route-meta layout union

The vite-plugin-vue-meta-layouts layout name is a hand-maintained union
in env.d.ts (not auto-generated). Task 8 created OrganizerLayoutV2 and
Task 3's boot-proof page sets meta.layout: 'OrganizerLayoutV2', but the
union lacked the v2 entries so a typed definePage failed vue-tsc.
Registers both v2 layouts (PortalLayoutV2 added now to pre-empt the same
gap when portal v2 lands). Completes Task 8 (RFC-WS-GUI-REDESIGN AD-G2).
