refactor: make checkbox component self-dependent by removing @radix-ui/react-checkbox dependency

[ruru-m07]

We need to refactor the Checkbox component to eliminate its dependency on @radix-ui/react-checkbox. The objective is to rebuild the component to make it fully self-contained, ensuring it no longer relies on any external libraries. This process will involve reimplementing its core functionality, updating the documentation to reflect the changes, and revising the tests to maintain alignment with the new implementation. The goal is to enhance flexibility, simplify maintenance, and reduce external dependencies for better control over the component's behavior.
