Updated XML comments in ResetEmailTemplateCommand and IEmailTemplateQuery to use HTML line breaks (<br/>) for example template types. This enhances readability in environments that render HTML in documentation. No functional changes were made.
Replaced EmailTemplateQueryBase record with IEmailTemplateQuery interface for email template queries. Updated all relevant commands, queries, and controller methods to use the new interface. Removed EmailTemplateQueryBase and migrated properties to implementing classes. Improved documentation to clarify query structure and Type property usage.
