chore(ci): add docker scripts

- add dockerfile for backend
- add docker-compose with backend details
- update nestjs packages
- add more excluded directories to tsconfig
- add dummy query due to graphql constraint
- add function to run pending migration at startup
- update createJwtOptions on ConfigService
