Refactor: Create shared AttachmentService and AttachmentModel

- Created common AttachmentService for all modules (app/Services/) - Created common AttachmentModel (app/Models/) - Created common migration (app/Database/Migrations/) - Updated Tasks module to use shared AttachmentService - Added Twig functions: format_filesize(), get_file_icon() - Removed duplicate TaskAttachmentModel and task_attachments migration - AttachmentService can be used by any module: task, deal, contact, etc.
