Docker: Hotfix ENV variable

[Ayush8923]

Summary

• Removed hardcoded POSTGRES_SERVER: db override from prestart, backend, celery_worker, and celery_flower services in docker-compose.yml.
• Services now inherit POSTGRES_SERVER from .env via env_file, allowing the same compose file to target either the local db container or a remote host (e.g. RDS) by simply changing .env.

Checklist

• Ran fastapi run --reload app/main.py or docker compose up in the repository root and test.
• If you've fixed a bug or added code that is tested and has test cases.

Poem

🐰 A variable vanished without a trace,
Four services freed from that database place,
The config grew lighter, the compose file so clean,
Environment variables, no longer seen!
Hop hop, the cleanup is done! 🎉
