Enhance inbound management by removing MaxClients property

- Removed the MaxClients property from Inbound-related data models, including InboundDto and PublishInboundCommand.
- Updated related methods and handlers to reflect the removal of MaxClients, ensuring consistent behavior across the application.
- Adjusted API documentation and frontend components to remove references to MaxClients, streamlining the inbound publishing process.
- Enhanced logging in command handlers to handle node unavailability scenarios during user actions.
- Improved database schema and migrations to align with the updated data model.
