Issue:
[BUG] remove redundant DB calls when FRM feature is not enabled

### Bug Description

FRM is a payment feature which is integrated in HyperSwitch behind `frm` feature flag. There are some DB queries (which are generally not behind a feature flag) which are being executed even when `frm` feature is disabled.

### Expected Behavior

Underlying DB queries should be executed only when the feature which requires it is enabled. In this case, FRM DB queries should be executed only when `frm` is enabled

### Actual Behavior

FRM DB queries are being executed regardless of `frm` feature flag
