refactor(config): add network configuration and dependencies for inter-service communication

- Configure flaresolverr and free-games-claimer to use a shared bridge network
- Explicitly set container name for flaresolverr and declare network dependency
- Define custom bridge network `fgc-network` for isolating service communication

This ensures services can reliably communicate over Docker's internal DNS while maintaining network separation from other containers.
