Geopolitical

Fixes:

- Fixed the issue where the glowing sword didn't appear // Replaced by an End Rod particle trail in the attacked chunk

- Fixed boss bar spam // Boss bars are now sent exclusively to players whose nation is directly involved. Traveling through other players' chunks → no more boss bars.

- Fixed duplicate messages // Capture messages (25%/50%/75%) now only appear in chat, visible to everyone. The action bar continues to display territory info upon entry.

Improvements:

- Boss bar colors // Two separate boss bars per capture:

- Attackers see: Blue (0-50%) → Green (50-100%)
- Defenders see: Yellow (0-50%) → Red (50-100%)
