Support to fetch bank records before start of fiscal year (old records)

[marination]

Issue:

• Currently when Bank Accounts are synced, the consent token is generated for 3 months
• This consent token has the upper limit or the start date from where bank transactions can be fetched
• The start date is assumed to be the current fiscal year's start date, which may not be what the user wants
• Kosma throws an error if older transactions are fetched beyond the consent's start date

Cases:

1. New setup > User has never fetched accounts or statements > User wants to start from 2018 > Daily transaction updates will be as usual (starting from the last synced date to today)
2. System is in use > User wants to fetch old transactions from some point (manually)

Possible Solution: Case 1 :

• Prompt user for a start date while fetching bank accounts for the first time (check if any bank with kosma ID)

Case 2:

• Use Flow API > ask user for start and end date > user will have to authenticate again > fetch
