[FEATURE] Add Docker Compose setup for local development

[EQuBitC18]

Feature Summary

Add an official Docker Compose setup that starts the Tezrisat backend and frontend together for local development.

Problem/Use Case

Tezrisat currently offers script-based local setup, but there is no containerized development path. That makes onboarding less reproducible across machines and raises the support burden for contributors who prefer Docker-based workflows.

Proposed Solution

Add:

a backend Dockerfile
a frontend Dockerfile
a docker-compose.yml for local orchestration
persistent volumes for sqlite/media
environment wiring from .env
concise docs for common workflows (up, down, rebuild, logs)

Alternative Solutions

No response

Priority

Would be helpful

Feature Scope

Deployment/Infrastructure

Additional Context

The repo currently contains local setup scripts under scripts/, but no docker-compose.yml and no service Dockerfiles.
