Subject: [PATCH] Refactor SupplierTest to use permission setup function and
 enhance phone number validation tests

- Introduced `giveSupplierPermissions` function to streamline user permission setup for supplier tests.
- Updated all supplier-related tests to utilize the new permission setup function.
- Enhanced phone number validation tests to accept various formats and special characters.
- Removed redundant tests related to unsupported phone number formats.
- Consolidated tests for supplier creation and updates to improve readability and maintainability.
