fix: unable to create manual / auto asset depreciation entry when cost_center is mandatory (#26912)

Summary : unable to create manual / auto asset depreciation entry when cost_center is mandatory

Reason: Though we are calculating value for depreciation_cost_center, it is not passed in credit_entry(it is passed in debit_entry) and this prevents creation of manual / auto asset depreciation entry when cost_center is mandatory

Solution : pass already calculated depreciation_cost_center value in credit_entry (in line with, already done as in debit_entry)
