Terminated agents (e.g. from rejected hire approvals) were visible in
GET /companies/:companyId/agents and GET /companies/:companyId/org because
list() and orgForCompany() had no status filtering.
- Add ne(agents.status, "terminated") filter to both queries
- Add optional { includeTerminated: true } param to list() for callers
that need all agents (e.g. company-portability export with skip counting)
- orgForCompany() always excludes terminated (no escape hatch needed)
