chore: update docker-compose and entrypoint script for improved configuration

- Updated web UI access URL format in docker-compose file.
- Added GATEWAY_BIND environment variable for flexible gateway binding.
- Modified entrypoint script to use GATEWAY_BIND variable and ensure proper directory setup and permissions.
- Changed user context for executing the entrypoint script for Phala CVM deployment.
