Improves tree and ground tile appearance

Refactors tree spawning and rendering:
- Adds seasonal color variations for trees via scripts.
- Introduces `ColorStorage` to manage tree and grass colors
- Removes unused code from tree spawning logic.
- Adjusts ground tile color for better visual appeal.
- Hides debug text on ground tiles.
