fix: batch nos in packed items (bp #26105)

* test: batch info in packed_items

* fix(ux): make packed items editable

* refactor: allow custom table name for set_batch

In some doctypes there are multiple child tables requiring batched
items. This change makes the function a bit more flexible.

* fix: Auto fetch batch_nos in packed_item table
