Description

Described in #6719

This PR introduces below changes

• get_network_txn_id fn in IncomingWebhook trait
• implement this new fn for Adyen for retrieving the network txn ID
• consume this fn in core flows for updating network_transaction_id in payment_methods table

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

Helps persist network transaction IDs for connectors in case it was not present in Authorize or Capture responses but instead sent in the webhook!

How did you test it?

• Ensure Adyen is configured in HS, along with webhooks!
• Ensure network_tx_reference (field in Adyen) is not returned in Authorize or Capture response
• This field should be populated in DB once webhooks are received (provided this field was also returned)

network_transaction_id is populated after receiving webhooks

Checklist

• I formatted the code cargo +nightly fmt --all
• I addressed lints thrown by cargo clippy
• I reviewed the submitted code
• I added unit tests for my changes where possible
