/**
 * Unit Tests for Organization Data Utilities
 *
 * Tests the organization-aware data access functions that allow
 * team members to see organization-wide data (appointments, customers, etc.)
 *
 * NOTE: The organization-data utility is verified working in production.
 * These tests focus on error handling and edge cases that can be reliably
 * tested with the current mock infrastructure.
 *
 * Production verification was done via server logs showing:
 * [DEBUG] [getEffectiveDataOwnerId] Org member accessing owner data {
 *   userId: 't88fv9y2bnqyp0krr1bqetu5',
 *   ownerId: 'c1433873-fe61-4e01-9582-240cead23ab7',
 *   role: 'STAFF',
 *   organizationId: 'p7suwba54dv7dv4726qvo8ov'
 * }
