Magento 2 Sameday Validation Fix

A Magento 2 module that fixes the Sameday shipping method to properly validate the Country field, which triggers shipping address validation and saving during checkout.

🚀 What This Module Does

This module solves a critical issue with the original sameday/magento2-plugin where:

• Problem: The shipping address is only saved when the "Country" field contains a valid value and passes Magento's default validation
• Root Cause: The Sameday plugin doesn't add validation rules for required fields like country_id, preventing the shipping address from being updated and saved
• Solution: This module adds proper validation rules for the Sameday shipping method that include required field validation for:
  • country_id (Country field)
  • postcode (Postal code)
  • region_id (Region/State)
  • region_id_input (Region input for manual entry)

🔍 Why This Fix Is Needed

In typical Magento 2 shipping method implementations (like tablerate), validation rules are properly defined to trigger address validation. However, the Sameday plugin was missing these crucial validation rules, causing:

1. Country field validation to be skipped
2. Shipping address not being updated when Sameday is selected
3. Incomplete address data being saved
4. Potential checkout issues and shipping calculation problems
