Feat: Allow Disassembly Based on BOM Without Work Order

[saista2]

Is your feature request related to a problem? Please describe.

When someone transitions from the old system to ERPNext, the work order does not exist at that time.

Repack keeps the output as an FG item and the input as raw materials by default, making it very difficult to reverse when there are 150 material input items.

On the other hand, Disassembly performs the expected operation in one go.

It would be beneficial to consider ignoring the Work Order (WO) validation, as it is a simple change that could help in several manufacturing scenarios.

For example, in cases where different operations are carried out via subcontracting, users may not want SFG (Semi-Finished Goods) items to be created at each stage.
