feat: implement checkbox component (#9)

* feat: implement Checkbox component for checkbox management This component encapsulates functionality for creating, removing, and changing the state of checkboxes. It utilizes strict mode and imports necessary functions from respective modules for checkbox creation, removal, and state change. The constructor ensures that the provided configuration is verified before initialization. * feat: implement checkbox creation function This function creates a checkbox element based on the provided configuration. It utilizes strict mode and imports necessary functions for verifying the configuration and setting attributes. The checkbox element includes an icon and attributes such as ID, class, state, group name, and target ID as specified in the configuration. * feat: implement checkbox state management function This function handles the change of checkbox state based on user interaction. It utilizes strict mode and imports necessary functions for verifying the configuration. The function toggles the checkbox state, updates the checkbox icon accordingly, and manages the targets associated with the checkbox. * feat: implement checkbox removal function This function removes a checkbox element from the DOM based on the provided configuration. It utilizes strict mode and imports necessary functions for verifying the configuration. Additionally, it removes associated items from local storage to maintain data consistency. * refactor: update import paths for module resolution Updated import paths in component files to use module resolution aliases defined in jsconfig.json. This change improves code readability and maintainability by replacing relative paths with aliases. * refactor: merge files into one Combine multiple files into a single file to reduce unnecessary module creation. This change simplifies navigation and improves codebase organization. * test: ensure event remover function works properly Add tests for the removeEvents function to verify that event listeners are correctly detached from elements. Ensure proper error handling is in place when the element or events are missing. TODO: In the browser, managing localStorage works, but in tests, it is quite tricky! This is still in process! Try to research more about this. * style: expand print width to 100 characters Adjusted code formatting to adhere to a maximum print width of 100characters, improving readability and consistency across the codebase. * fix: remove console logs Eliminate console logs from the code to clean up the output and improve code readability.
