fix: throw bad request while pushing duplicate data to redis

[dracarys18]

Type of Change

• Bugfix

Description

Throw bad request when duplicate data get's inserted in redis.

Motivation and Context

Currently we are throwing 500 when you insert duplicate data in redis. This is quite misleading as it's a genuine error. So throw 400 when you try to push duplicate data.

How did you test it?

• Create 2 payments with same payment_id and the 2nd response will be 400 bad request.
