Fix: Deduplicate error logging in orphaned users sync flow

[Copilot]

The flow creates an error record for every group where transitive member fetch fails. In environments with 100+ groups lacking proper Graph API permissions, this generates 100+ error emails per run.

Changes

• Added deduplication: Introduced TransitiveErrorLogged boolean variable to track if error has been logged in current run
• Wrapped error creation: Error logging now conditional on TransitiveErrorLogged == false, set to true after first log
• Fixed typo: "presnce" → "presence" in error message

Flow Logic

Initialize TransitiveErrorLogged = false
  └─ Apply_to_each_group
      └─ Get_Transitive_members (fails)
          └─ Check_if_error_already_logged
              └─ If false:
                  ├─ Log error once
                  └─ Set TransitiveErrorLogged = true
              └─ Continue with flat group members fallback

Impact

• Reduces error notifications from N per failing group to 1 per run
• Preserves error visibility for investigation (includes flow run URL)
• No change to group processing or data accuracy
• No configuration changes required
