Fixes duplicated PHP tag in published migration stub

Removes a duplicated opening PHP block that caused published migrations to contain two <?php tags and trigger parse errors during artisan migrate.

Ensures the photometry migration stub is published by the service provider and that the published migration is idempotent and rollback-safe. Also removes a redundant generated migration to avoid duplicate migrations.

+## Version 6.7.2
+
+Fixed:
+
+- Removed a duplicated PHP block from the photometry migration stub so published migrations no longer contain two `<?php` tags (preventing parse errors when host apps run `php artisan migrate`). The corrected stub is `src/database/migrations/add_photometry_to_comets_orbital_elements_table.php.stub` and contains a single idempotent migration class.
+- Ensured the package publishes the photometry migration stub (service provider updated) and verified the migration is idempotent and rollback-safe.
