feat(config): Add logs buffer size config

[tab]

• Extend Config struct to include Logs.Buffer
• Update default configuration to set Logs.Buffer
• Modify hub and server to use the new buffer size

[Copilot]

Pull request overview

This PR adds configurable logs buffer size support to the application. Previously, the logs buffer size was hardcoded; now it can be configured via the YAML configuration file.

Changes:

• Added a new Logs.Buffer configuration field with validation
• Renamed the constant from LogsBufferSize to SocketLogsBufferSize for clarity
• Updated the hub and server implementations to use the configurable buffer size
