feat: enhance team member resolution and activity components

- Introduced a new method to avoid duplicate member names in TeamMemberResolver, ensuring case-insensitive uniqueness.
- Updated ActivityItem and ActivityTimeline components to utilize local member names for improved recipient qualification checks.
- Added tests to validate the handling of dotted names and deduplication in cross-team messaging scenarios.
