Refactor TerritoryLayer and TerritoryWebGLRenderer for contest management

- Introduced contest management in TerritoryLayer, replacing previous transition handling with a new system for managing contests between tile owners.
- Added methods to handle contest state, including starting, updating, and expiring contests.
- Updated TerritoryWebGLRenderer to support rendering contest data, including new textures and uniforms for contest owners, IDs, and times.
- Enhanced rendering logic to visually represent contest states, including color changes and border effects during contests.
