feat inv dim propagation

[robproject]

Description

• Add inventory dimensions to get_handling_unit method, using cached list of dimensions, for update of all target child table documents.
• Refactor Handling Unit inventory dimension creation into method to be shared by any app for Inventory Dimension creation.
• Add custom_carry_forward field to Inventory Dimension DocType for use in propagate_inventory_dimensions.
• Add propagate_inventory_dimensions method as before_submit hook on Stock Entry to enable below behavior. BEAM's handling_unit.py is updated to not overwrite target_handling_unit if it has a value set already, unless the HU qty and transfer qty don't match.

custom_carry_forward	Transfer qty	to_handling_unit result
On	qty == stock (full)	Same HU (conserved)
On	qty != stock (split)	New HU (BEAM overrides)
Off	any	New HU (BEAM default)

• Update tests.
• Syntax changes in scan/init.py for v16: pass frappe._dict(), use SUM dict in frappe.get_all()
• Similar to 135 preserve complete hu #137 but applies to any configured Inventory Dimension and accounts for qty splitting.

📝 Draft Changelog Entry

Changelog

This update adds inventory dimension propagation functionality to Stock Entry documents. When a Stock Entry is submitted, inventory dimensions are now automatically carried forward to handling units based on configuration settings.

A new custom_carry_forward field has been added to the Inventory Dimension DocType. When this field is enabled, handling units are preserved during full quantity transfers. For partial quantity transfers, new handling units are created as before. When the field is disabled, the default behavior of creating new handling units applies to all transfers.

The handling unit creation process has been refactored into a shared method that can be utilized across applications for inventory dimension creation. The get_handling_unit method now includes inventory dimensions using a cached list to ensure all target child table documents are updated consistently.

Technical updates include syntax changes in the scan module for compatibility with Frappe v16, including the use of frappe._dict() and SUM dictionary operations in frappe.get_all() calls.

@robproject This is a nice feature!

I have two other versions of BEAM that are customized a little differently. Need to try combining them all for this. It started with only this PR but each system diverged.

Draft Changelog Entry

Changelog Entry

This update adds inventory dimension propagation functionality to stock entries. When submitting a stock entry, inventory dimensions are now automatically carried forward to child table documents based on configuration settings.

A new custom_carry_forward field has been added to the Inventory Dimension DocType. When enabled, this field preserves the original handling unit during full quantity transfers. For partial quantity transfers (splits), a new handling unit is created instead. When the setting is disabled, the default behavior of creating a new handling unit applies to all transfers.

The handling unit creation process has been refactored into a shared method that can be utilized by any application for inventory dimension creation. The system now uses a cached list of inventory dimensions to retrieve and apply them to all target child table documents during stock entry processing.

Technical compatibility updates have been made to support Frappe v16, including syntax adjustments in the scanning module.
