RDKEMW-16333: update Thunder power manager to use a bool for NSM

[jthomp007c]

Reason for change: IARM Power Manager used a JsonObject to query the Networked Standby Mode flag. Thunder Power Manager uses a bool

Test Procedure: Confirm that NSM is currently enabled: curl --request POST --url http://127.0.0.1:9998/jsonrpc --header
'Content-Type: application/json' --data '{ "jsonrpc": "2.0",
"id": 1234567890, "method":
"org.rdk.PowerManager.1.getNetworkStandbyMode", "params": {} }' must return
{"jsonrpc":"2.0","id":1234567890,"result":true}

Put the device into deep sleep, either by performing normal NSM test or SetPowerState STANDBY followed by SetPowerState DEEPSLEEP

Confirm that ctrlm logs "NSM is "

Risks: Low

Priority: P0

Pull request overview

Updates the ControlMgr Thunder PowerManager integration to query Network Standby Mode (NSM) as a boolean result (matching Thunder PowerManager behavior) rather than parsing it from a JsonObject.

Changes:

• Added a call_plugin_boolean() helper to invoke Thunder methods that return a boolean.
• Updated PowerManager’s get_networked_standby_mode() to use the new boolean helper and simplified response handling.
• Minor docstring grammar fixes in the Thunder plugin base header.

• The Doxygen for property_get doesn’t match the function signature: it references method and params, but the function takes property and has no params argument. This makes the API confusing for callers; update the parameter names/descriptions to reflect the actual arguments.

     * This function is used to get a Thunder Plugin property.
     * @param method The method in which the user wants to call.
     * @param params The WPEFramework JsonObject containing the parameters for the call. (We can't include WPEFramework headers in controlMgr .h files as their logging macros clash)
     * @param response The WPEFramework JsonObject containing the response from the call.  (We can't include WPEFramework headers in controlMgr .h files as their logging macros clash)
     * @param retries The number of retries if the call times out.

• The Doxygen for call_controller lists the second parameter as @param params even though the third argument is response. This should be corrected to @param response to avoid misleading documentation.

     * @return True if the call succeeded, otherwise False.
