Description:

• Extends and improves click tracking all across the Reports according to the following proposals

- For these labels (Select, Date Input, Symbol, Date, Category Filter), 
we should set the "area_source" as the current page/screen the user is on.

- So if the user is on ledgers and the date input is clicked, 
we should send it with the event property area_source: "ledgers".
