refactor: Replace { x: number, y: number } type declarations with Point type

- Updated type declarations written as { x: number, y: number } to use the Point type as per requirements.
- Explicit names were used for variables by destructuring previously used object types.
- For example, scenePointer.x, scenePointer.y are now destructured as scenePointerX and scenePointerY.
- When a Point type was required as an argument, the `pointFrom` helper function was used to convert and pass the value.
