feat: update validation and exception handling, refactor controller routes, and enhance sales invoice item DTO

- Removed global validation pipe and added a new ValidationExceptionFilter for better error handling.
- Refactored controller routes to use underscores instead of hyphens for consistency.
- Updated CreateSalesInvoiceItemDto to include new fields: quantity, unit_type, and payload.
- Modified CreateSalesInvoiceDto to enforce items as an array with a minimum size.
- Added Enums module to provide gold karat values through a dedicated endpoint.
- Introduced new columns in the database schema for sales invoice items and goods.
