- Validation: Zod enums for leave_type/status, numeric transforms on
  foreign keys, VAT 0% coercion fix (Number(v)||21 → v!=null checks)

  and project_logs access checks, trips users filtered by trips.record

  duplicateOffer, bulkCreateAttendance, createLeave, scope-templates,
  leave-requests, company-settings, profile updates
