NXT event roster and name-tag workaround advice

For GiveCampus integrations and API.

Use GC guest/activity rosters to reconcile actual attendance and inspect NXT errors/matched constituent identities. Do not repeat the quoted universal claim that activities cannot export: current code supports separately exporting event activities when configured. Name-tag workflow, the actual missing roster and promised future release need current operational/provider confirmation. Manual NXT edits can be overwritten by sync; no extra CRM event was created.
