- Core/Organisation/OrgTemplate: format, export, parse, structural checks.
  Export empties every credential (nested, name variants) and names it;
  a template that carries one is refused.
- OrgAdministration: ExportTemplate, PreviewTemplate (problems, warnings,
  every text in full), ImportTemplateAsync - only with confirmation, units
  before agents, own workspace per unit, doctrines, model and budget factor
  overridable, templateOrigin on every unit and agent.
- Endpoints GET /organisation/template, POST .../preview, POST .../import;
