feat(rbac): no role at registration; invitation-based membership; nav gating

- Registration no longer asks for a role/persona (removed the role select +
  allottee block); crm.account.register sends no persona.
- New users have no permissions → the sidebar now shows only Dashboard + Profile
  for them, gated on crm.account.me (membership + permissions). Members see the
  areas their permissions allow.
- Add /portal/invite?token=… : accepts the invite for a signed-in registered
  user, or routes an unregistered invitee through register/onboarding, which
  redeems the stashed token on completion (granting the invited role).
- Team Management: 'Copy link' on pending invites builds the invite link from
  the invitation token (no email delivery yet).
