Issue:
Bug: feat(analytics): implement currency conversion to power multi-currency aggregation



## Current Behaviour

The total amount calculated for all payment analytics buckets related to amounts is incorrect because currency conversion is not being applied before summing the values. As a result, amounts in different currencies are being added together, leading to an inaccurate total.

## Proposed Changes

- introduce `<AMOUNT_RELATED_FIELD>_in_usd` fields to convert and store value in `USD`
- introduce total_in_usd to store the total value in usd
- Generally provide currency_conversion facility to metrics function for other future use cases

## Description
- implemented currency_conversion for calculating values of amount related metrics from their currency (i.e `INR`) to 
`USD` and store it in a separate field variant I created `<fieldname>_in_usd`
- Implemented a total_amount_in_usd variant for all the total fields related to amounts in query Metadata

## 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).

The total amount calculated for all payment analytics buckets related to amounts is incorrect because currency conversion is not being applied before summing the values. As a result, amounts in different currencies are being added together, leading to an inaccurate total.

### Dependency

This functionality depends on `currency_conversion` crate directly to fetch exchange rates.

## 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)?

## Testing for various other scenarios

### by tweaking `development.toml` we can create these scenarios 
```toml
[forex_api]
call_delay = 30
local_fetch_retry_count = 5
local_fetch_retry_delay = 1000
api_timeout = 20000
api_key = "YOUR PRIMARY API KEY HER" # set this value to anything else to invalidate it
fallback_api_key = "YOUR FALLBACK API KEY HER" # set this value to anything else to invalidate it
redis_lock_timeout = 2600
```

by setting `call_delay` to 30s we can check for the fetch cycle and redis updates.

1. When primary api isn't working (invalidating the primary api key)

 #### API response : 200

2.  when both keys are invalidated
