Support complex datatypes in json input to SCRIPT AAF_RUN_QUERY_HANDLER

[ckunki]

Calling EXECUTE SCRIPT AAF_RUN_QUERY_HANDLER() accepts a json string as input.
The key parameters in the json is currently required to be a string and passed to x as a string.

When the user provided a data type other than string then

• Simple data types like float, int, bool will be converted to a String,
• while a Json object or an array is represented as a string value with an unusable reference, e.g. table: 0x14823bd38580.

The current ticket requests to support the complex datatypes in json input by converting them into a json string:

Json input	current conversion	Rating	Expected conversion
"parameter": true,	"true"	✅	"true"
"parameter": 123,	"123"	✅	"123"
"parameter": 1.3,	"1.3"`	✅	"1.3"
"parameter": [ "bla-bla" ],	"table: 0x14823bd38580"	❌	'[ "bla-bla" ]'
"parameter": { "a": 123 ],	"object: 0x14823bd38580"	❌	'[ "a": 123 ]'
omitting the entry parameters	string "nil"	❓	(TBC)
