feat(form): add loading state and replace custom switch component

This commit introduces a loading state for form submissions and replaces the custom switch component with a third-party library for improved user experience and maintainability.

- Adds `react-switch` as a dependency to replace the custom-built switch component, providing a more robust and feature-rich solution.
- Implements a loading indicator on form submission buttons and in the confirmation modal by utilizing the `useIsMutating` hook from TanStack Query. This provides clear visual feedback to the user during asynchronous operations.
- Creates a reusable `FormFooter` component to encapsulate the submit and cancel buttons, centralizing the form submission logic and loading state.
- Refactors the company create/edit forms to use the new `FormFooter` and `react-switch` components.
- Moves the `BreadcrumbItem` type to a shared types file for better code organization.
