Refactored implementation to support multiple STA entries per message (spec compliant)
Changed the struct to json format to carry cacr information from UWM to OneWifi.

Pull request overview

This PR updates the EasyMesh Client Association Control Request (CACR) handling to accept a JSON sub-document from UWM and to apply the request to multiple STAs per message, rather than a single STA.

Changes:

Switched CACR payload handling from a binary struct (client_assoc_ctrl_req_t) to a JSON subdoc parser (parse_client_assoc_ctrl_json()).
Added multi-STA processing loop for StaMacList and per-STA ACL timer scheduling/cancellation tracking.
Extended kick_details_t to carry a scheduler timer ID for cancel support.

File	Description
source/core/wifi_ctrl.h	Extends `kick_details_t` with a `timer_id` field to track scheduled ACL removal timers.
source/apps/em/wifi_em.c	Implements JSON parsing for CACR, multi-STA handling, and pending timer tracking/cancellation.
include/wifi_base.h	Removes the old binary CACR request struct (`client_assoc_ctrl_req_t`) now replaced by JSON payloads.

The error cleanup: path only frees kick_details, but when kick_details->kick_list has been allocated (e.g., strdup() succeeded) this leaks memory. Free kick_details->kick_list first (it is safe to free(NULL)).

cleanup:
    if (kick_details) {
        free(kick_details);
    }
