bugfix: doi-registration: Refactor XSLT and Vue components for improved data validation and conditional rendering

- Updated doi_datacite.xslt to include conditional checks for empty values in creators, titles, subjects, contributors, dates, rights, sizes, formats, descriptions, and geoLocations to ensure only non-empty elements are rendered.
- Enhanced the handling of TitleAbstract and TitleAbstractAdditional templates to only output descriptions if the Value attribute is not empty.
- Modified the Doi.vue component to clean up the import statements and commented out unused warning display code for clarity.
