Set Bank Clearance Data within Mint

[Starktail-Christo]

Currently, you are able to see transactions that have not been marked as "Cleared" under the Bank Clearance Summary, but you still need to go back into ERPNext on the "Bank Clearance" page to set the clearance dates.

It would be helpful if this functionality could also be handled directly from the Mint app, without having to switch back to ERPNext.
