Update KOMOJU Plugin for WooCommerce Cart Checkout Block & HPOS

[Dinwy]

Description:

This PR updates the KOMOJU Payments plugin to ensure compatibility with WooCommerce's Ceckout block & High-Performance Order Storage (HPOS) feature. The following changes have been made:

Compatibility Declaration:

• Added code to declare compatibility with WooCommerce's 'cart_checkout_blocks' and 'custom_order_tables' features.

Payment Method Data Handling:

• Added a check to ensure the plugin does not operate on the 'order-received' endpoint to avoid unnecessary session creation.

Order Meta Data Handling:

• Replaced update_post_meta calls with WC_Order's update_meta_data and save methods to ensure compatibility with HPOS.
• Updated the save_komoju_meta_data function to use update_meta_data instead of update_post_meta.

Fix timing issue in the test

• There was timing issue in cypress that it was testing without signed in correctly. So, I adjusted the process about how to sign in.

After this get merged, I will update version to 3.1.4 and will publish it.
If you have any concerns or questions please let me know!
