OFBIZ-13248 Calculate labor cost when production run is completed

Implemented the automatic calculation and recording of labor costs when a production run is completed. This is achieved by creating TimeEntry records associated with the production run task, using a specific labor rate type.

Changes made:

Data (Seed/Demo):

• Added FLC (Factory Labor Cost) RateType in ManufacturingSeedData.xml.
• Added sample PartyRate data in ManufacturingDemoData.xml to support testing of labor cost calculations.

UI Labels:

• Introduced new UI labels in ManufacturingUiLabels.xml for labor cost visibility.

Service Logic (ProductionRunServices.java):

• Enhanced the production run completion flow to calculate labor hours from the reported task time.
• Automatically invokes the createTimeEntry service with rateTypeId="FLC" to record the labor cost for the work effort.

Thanks Pierre Smits and Jacopo for design details on ticket.
