feat(architecture): Implement decoupled modifier architecture

This commit introduces a major architectural refactoring to improve the maintainability, extensibility, and testability of the application.

Key changes include:
- **IAppModifier Interface:** Defines a clear contract for all application-specific modifiers.
- **BaseAppModifier Abstract Class:** Provides common implementations for shared modifier logic, reducing code duplication.
- **Refactored Concrete Modifiers:** Existing modifier classes now inherit from BaseAppModifier, focusing on their unique application-specific logic.
- **ModifierFactory:** Centralizes the creation of modifier instances, decoupling the UI from concrete implementations.
- **Updated FormMain.cs:** The main UI now interacts with modifiers through the IAppModifier interface and uses the ModifierFactory, significantly reducing coupling and simplifying UI logic.

This refactoring adheres to principles of abstraction, encapsulation, and polymorphism, making the codebase more robust and easier to extend with support for new applications in the future.
