Reviewing the audit log

Every change to inventory and team membership is appended to the audit log with timestamp, actor, and a one-line summary.

1. Open Team › Activity log.
2. The log lists every event in reverse-chronological order. Filter by member, action category (members, invitations, roles, inventory, reports), or date range.
3. Tap an entry to see the full diff — what changed, before and after.
4. Use Export CSV to download the log for compliance review.

Screenshots for this workflow are pending. The production TeamActivityScreen imports dart:html directly for its CSV-export download, which prevents it from compiling under the wiki capture harness (Flutter test on the host VM). Once the export path is moved behind a kIsWeb guard or routed through a platform-abstracted service, this page will be filled in.
