feat(companies): implement companies page with data table

This commit introduces a new "Companies" page to the dashboard, providing a comprehensive view of company data in a sortable and paginated table.

Key changes include:
- A new page at `/companies` to display the data table.
- A new API route `/api/companies` that serves mock company data.
- A `CompaniesTable` component built with `react-table` featuring sorting, pagination, and search functionality.
- Reusable `TablePagination` and `TableActions` components to support the table.
- The `moment` library has been added as a dependency to format dates within the table.
- A new `CrossIcon` has been added for UI controls.
- The `InputGroup` component is enhanced with an `autoComplete` prop.
- A link to the new "Companies" page has been added to the sidebar navigation.
