- Updated the speaker form dialog to include additional information about MikroTik connections and logging commands.
- Modified the BIRD configuration to include logging to stderr for better visibility during operations.
- Adjusted the Docker Compose configuration to ensure proper network settings and sysctl configurations for BGP functionality.
