feat(aihr): add owner identity profiles for realtime practice

- remove owner-impatient persona; owner-calm renamed to 业主
- aihr_realtime_owner_profile table (tenant+project unique, enabled,
  version) with formal migration
- admin CRUD under moderator role gate; project code validated against
  org snapshot and project name taken from snapshot authoritatively
- employee endpoint returns display-safe fields plus defaultProfileId
  from the employee's own community; profile body never exposed
- session creation renders {community}/{profile} server-side; client
  text can never enter instructions; invalid profileId rejected,
  default resolution fails closed
- duplicate create returns 409
