Pull Request Overview

This PR updates how audit properties are handled in the DbContext by replacing custom SaveChanges overloads with interceptor-based behavior and updating tests to register these interceptors. Key changes include:

• Removing default initialization values for created audit fields in test entities
• Updating test setups for DbContext to register Creatable, Modifiable, and SoftDelete interceptors
• Refactoring BaseDbContext to implement IAuditContext and removing legacy tagging methods

• Ensure that retaining a previously set AuditUser (instead of overriding it with the current caller's information) is the intended behavior; if the audit should reflect the current user, consider updating AuditUser accordingly.

AuditUser = AuditUser ?? UnknownUser;
