fix: Revenue and Customer Count only in date range in Customer Acq. Report

[abhishekbalam]

Improvement on this:
#22075

The revenue was being calculated from
the 1st invoice ever created, and hence
is too high.

Also territorywise customer counts were wrong,
for the same reason, as monthly compensates for
report From Date by default.

So limiting counting of customers and revenue
within filter dates but considering all invoices
till To Date to determine new customers.

Changes only done in the last function, had to
convert spaces to tabs as I didn't have the last
PR branch. From Line 162...
