fix(trustpay): add connector request reference ID generation for v2 f…

[ayush22667]

Type of Change

• Bugfix
• New feature
• Enhancement
• Refactoring
• Dependency updates
• Documentation
• CI/CD

Description

The length of receipt for Trustpay order request should not exceed 35 characters. So added generate_connector_request_reference_id specific to trustpay which generates less than 35 charcters.

Additional Changes

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

Motivation and Context

TrustPay API rejects payment requests when the reference field exceeds 35 characters, causing payment failures so now after this it generates uuid of 35 character for reference field specific to trustpay.

How did you test it?
