ref(cells): Organization invites go the correct org scoped routes (#112137)

Updates get_invite_link to generate org-scoped invite URLs
(/accept/<org_slug>/<member_id>/<token>/) instead of the legacy no-org
format (/accept/<member_id>/<token>/).

This is a prerequisite for removing the legacy no-org invite route and
ensuring this works even when multiple cells are configured.
