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.
Changed namespace from .Commands.Reset to .Commands for ResetEmailTemplateCommand and its handler. Reformatted and re-indented code for readability; no functional changes were made.
