Add support for targeting announcements to specific usergroups or individual players.
- Add 'target' field to store a usergroup to filter recipients
- Implement recipient filtering logic that prioritizes explicit player lists over usergroup lists over preset target
- Update net.Broadcast() to net.Send() when specific recipients are selected
- Parse scope parameter from client to determine targeting type (all/group/players)
- Return early if no valid recipients are found after filtering
