feat: multiple purchase invoice in asset repair doctype

[rahulgupta8848]

Background/Context

1. In the “Asset Repair” doc type we can add only one single purchase invoice in a single record.
2. However, in real case repairs expenses incurred can be booked via multiple invoices.
3. Also, repairs services for an asset can be availed from more than one supplier. We are not able to select multiple invoices while making a repair entry.

Solution Summary

1. Use child table to select multiple purchase invoices in the one asset repair (as shown in the below screenshot).
2. Auto calculate the repair cost on the basis of all the purchase invoice amount.
3. Remove the single purchase invoice standard field from the doctype.
