Refactor attachment cropping functionality to support multiple variants

- Introduced AttachmentCrop model to manage crop variants for attachments.
- Updated Attachment model to remove direct crop fields and establish relationships with AttachmentCrop.
- Modified AttachmentService to handle storing and updating multiple crop variants (desktop and mobile).
- Adjusted validation rules to accommodate new crop structure.
- Updated database migration to create attachment_crops table and migrate existing crop data.
- Refactored tests to ensure compatibility with the new cropping structure and validate multiple crop variants.
- Enhanced documentation to reflect changes in attachment handling and cropping capabilities.
