- Add server-side `<admin>/layout.tsx` that redirects non-super-admins to
`/[portSlug]/dashboard`. Closes the gap where any authed user could
guess the URL and reach Users / Roles / Audit Log / Backup.
- `withAuth` super-admin branch now 404s when the requested portId does
not match a real port row, preventing a compromised super-admin
session from operating against a fabricated portId.
- Portal JWTs now carry `aud: 'portal'` + `iss: 'pn-crm'` claims and
`verifyPortalToken` requires both, so a portal token can no longer be
replayed against the CRM session path or vice versa. In-flight tokens
(≤24h) will be invalidated once on deploy.
- `saved-views/[id]` PATCH and DELETE now do an explicit ownership
check before the service call, returning 403 instead of relying on
the service's internal userId filter.
