Issue:
Bug: feat(analytics): add `sessionized_metrics` for refunds (backwards compatibility) and `currency_conversion`



## Current Behaviour

- There is no `sessionized_metrics` module for refunds like there is for `payments` and `payment_intents`
- Update the existing metrics with `currency_conversion` usage.
## Proposed Changes

- create `sessionized_metrics` module for refunds
- implement `currency_conversion` for refunds analytics

Pull request description:
## Type of Change
<!-- Put an `x` in the boxes that apply -->

- [ ] Bugfix
- [x] New feature
- [x] Enhancement
- [x] Refactoring
- [ ] Dependency updates
- [ ] Documentation
- [ ] CI/CD

## Description
<!-- Describe your changes in detail -->
- Add sessionized metrics module and implement backwards compatibility.
- Implement currency conversion for refunds analytics

### Minor unrelated changes
- refactor inconsistent naming of fields in some places => [commit](https://github.com/juspay/hyperswitch/pull/6419/commits/08e53d63b5561163712bdfaefebed1caecdb793b)
- fix sankey incorrect formula => [commit](https://github.com/juspay/hyperswitch/pull/6419/commits/6ae2fb68290bf91a6d10178aa620893c3fd45846)
### Fixes #6417 
### Additional Changes

- [ ] This PR modifies the API contract
- [ ] This PR modifies the database schema
- [ ] This PR modifies application configuration/environment variables

<!--
Provide links to the files with corresponding changes.

Following are the paths where you can find config files:
1. `config`
2. `crates/router/src/configs`
3. `loadtest/config`
-->


## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->
- Refund metrics didn't had a `sessionized_metrics` module and implementation as were there in payments and payment_intents metrics
- Refund metrics weren't implementing currency conversion.
## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
