fix: use internal Docker network for backend-to-CMS communication

- Changed STRAPI_URL from https://cms.placebo.mk to http://cms:1337
- Added cms dependency to backend service
- This fixes Gateway Timeout errors when backend tries to fetch from Strapi
- Enables proper container-to-container communication
