Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

This PR adds support for “Real” client workflows across station-management and iperf steps, including new TDA endpoints and additional client model types.

Changes:

• Introduces wlan_emu_real_sta_mgr_t and wires it through test execution to handle real-client connect/disconnect requests.
• Extends JSON decoding and step execution for iperf and station management to support ConnectionType=Real, device metadata, and service preferences.
• Adds new endpoint types/URLs for real-client connection, disconnection, and iperf requests; also fixes IP validation logic.
