chore: update to v1.2.5 and simplify version management

🎯 Simplified Version System:
- Update frontend/backend to v1.2.5 in package.json and go.mod
- Frontend reads version from package.json directly
- Backend reads version from go.mod directly
- No environment variables needed for versioning

🔄 Automated Release Workflow:
- GitHub Actions automatically updates all version files
- Extracts version from Git tag (v1.2.5)
- Updates package.json, go.mod, docker-compose files
- Builds and pushes Docker images with proper tags
- Creates GitHub release automatically

🚀 User Experience:
- Just: docker compose up
- System auto-detects version from code
- Updates work with no manual setup
- Proper semantic versioning (MAJOR.MINOR.PATCH)

Ready for automated release!
