[REFACTOR]: [COINBASE] Add amount conversion framework to Coinbase

mrudulvajpayee4935 commented 3 weeks ago

:memo: Feature Description

Currently, amounts are represented as i64 values throughout the application. We want to introduce a Unit struct that explicitly states the denomination. A new type, MinorUnit, has been added to standardize the flow of amounts across the application. This type will now be used by all the connector flows.

Rather than handling conversions in each connector, we will centralize the conversion logic in one place within the core of the application.

:hammer: Possible Implementation

For each connector, we need to create an amount conversion function. Connectors will specify the format they require, and the core framework will handle the conversion accordingly.
Connectors should invoke the convert function to receive the amount in their required format.
Refer to the connector documentation to determine the required amount format for each connector.
You can refer this PR for more context.

🔖 Note: All the changes needed should be contained within hyperswitch/crates/router/src/connector/ , crates/router/src/types/api.rs , crates/router/tests/connectors/
