Refactor access card handling and update CLI output for tunnel operations

- Integrated `print_access_card` functionality into the `up` command for both tunneled and non-tunneled scenarios.
- Removed the deprecated `print_mcp_snippet` function from the session management flow.
- Updated the `tunnel_forwards` function to streamline port handling for LLM runtimes.
- Enhanced test cases to reflect changes in access card printing and MCP snippet logging.
