Add a page to the TUI to call a contract's public function

Should probably do it after https://github.com/archethic-foundation/archethic-cli/issues/50

The tricky part of this ticket is the `args` parameter. Since there are as many as we want and they can be of any type.
On the playground we have a list of json (1 json for each parameter).
Maybe we can use the same behaviour

Start by reviewing issue #50, since this work is intended to follow it, then compare the playground's handling of one JSON value per contract parameter. Define what the new TUI page must do for a contract's public function and arbitrary typed args; done means the page can invoke the function with those arguments.
