PR Summary

• New Template Components Added Five new template components have been added to help with formatting and exporting various kinds of data. These include a template for country data export, geographic reach export, initiative category export, initiative importing guidelines, and a simple "yes"/"no" data export.

• Controller Modifications The ImportOperation controller and ProjectCrudController have been updated to utilise the initiative import template for downloads. This switch ensures more efficient and well-formatted data importing.

• Improvement in Validation Rules To ensure the accuracy and consistency of date information, the ProjectRequest validation rules have been updated to enforce proper date format validation for the start_date and end_date fields.

• Enhancement in Project Data Import The ProjectImport class has been enhanced to provide row-by-row import control, enabling more precise and controlled data import processes. Moreover, modifications have been made to handle the import of projects and their linked geolocation data (continents, regions, countries) more efficiently. There are updates as well to ensure that example rows and instruction rows in the import template are correctly validated and handled during the import.

• Other Notable Changes The 'projects' sheet name has been updated to 'initiatives' which represents more accurately the data contained in it. New versions of software dependencies (maatwebsite/excel) have been added for improved functionality. A new dependency (spatie/laravel-ray) has also been added to assist in the development process.
