[Extensibility Request] issue 29640: use document type enum in blocked customer event

[Marko Aleksandric (AleksandricMarko)]

Summary

Extensions need the blocked-customer check to preserve extensible general journal document type values instead of reducing them to an option integer. This PR changes the event contract to use the Gen. Journal Document Type enum and publishes the enum value directly.

Source issue repository: microsoft/AlAppExtensions; issue number: 29640

Changes Made

• Customer.OnBeforeCheckBlockedCust - changed DocType from an option to the extensible Gen. Journal Document Type enum and removed the integer conversion across W1 and all existing layer counterparts.

Fixes AB#620150

Copilot

it is not allowed to replace type of parameter in OnBeforeCheckBlockedCust
instead, you need to create new event with updated parameters, to obsolete existing event and also all calls of existing event to surround with if not CLEAN

Implemented in commit a18ef8bb.

• Restored OnBeforeCheckBlockedCust with original Option DocType under #if not CLEAN29.
• Marked the legacy event obsolete.
• Added new enum-based event OnBeforeCheckBlockedCust2.
• Updated publishers to call the legacy event only in non-CLEAN builds and then the new event when not already handled.
• Propagated the same change across all affected layer files.
