Refactor functions to utilize a centralized state object for improved consistency and maintainability

Refactor functions to use a centralized state object

Modifies various functions to accept and utilize a `$State` parameter, replacing direct access to `$script:uiState` and module-scoped variables.

This change centralizes state management, improving code consistency and maintainability by passing necessary UI elements, data, and default configurations explicitly.
