fix(tools): support stringified HTTP request tables (#3565)

* fix(tools): support stringified HTTP request tables

Accept stored header and query tables after they are reloaded from UI JSON so HTTP requests keep their query strings and URL-encoded body handling intact.

* test: mock AuthType in async execute route

* test(tools): cover invalid stringified HTTP inputs
