Description

This is a following PR of https://github.com/juspay/hyperswitch/pull/5093 that implements significant changes to the way Cypress handles 4xx errors. Will go through it one by one:

• We now check if the error is 4xx and is not supported error in utils which is where defaultErorHandler have been moved. If yes, then we throw the error from Commons.js
• Removed unsupported error configs from all connector.js configs as we now have default case which takes of it
• Removed duplicate getValueByKey() as we now re-use the existing ones from utils
• Removed unused variables
• Used loops where ever possible
• logRequestId() could not moved to utils as the cy.task() used in that function can only be used in either spec file or helper file (commands.js)
• Connector auth issue has been handled with 55ae0b1 (#5128)
