I've configured the container names and linked the UI to the API.

Here's what I did:
- Added `container_name` for `api` and `ui` services in `docker-compose.yml`.
- Created `ui/src/apiClient.js` to configure the API base URL using the API container name (`http://planilla-api:4000/api`).
- Added `axios` as a dependency to the UI project.
- Ensured UI store files correctly import the new `apiClient.js`.

This will allow your UI to reliably connect to the API service using Docker's internal DNS resolution via container names.
