fix(auth, customers): Refresh page on logout and rename form field

This commit introduces two main improvements: ensuring a clean state after user logout and enhancing the clarity of the customer creation form.

The logout function in the `UserContext` now calls `router.refresh()`. This forces a page reload, preventing the user from seeing stale, authenticated data after logging out.

Additionally, the form field for assigning companies to a customer has been renamed from `company_ids` to `companies` in both the form component and the Zod validation schema. This refactoring improves code clarity and consistency. A related `console.log` statement was also removed.
