[BUG] dev-docker-compose.yaml still has the same bug from #9, plus incorrect README references

[Hector-Ha]

Description:

The bug reported in #9 was never actually fixed. The old docker-compose_dev.yml has been removed while adding the new dev-docker-compose.yaml, but the issue remains. In addition, README and README.GSoC are referencing old filenames

Reroduce:

1. Clone the repo
   git clone https://github.com/istSOS/istSOS4-gui cd istSOS4-gui/ui
2. Build and run with Docker Compose
   docker-compose -f dev-docker-compose.yaml up -d
3. Container starts but there is error sh: 1: next: not found
