Feature/remove bankconfiguration from bankservice (#14)

* moved configuration of banks from bankservice to plugin

* Refactor BankService and Plugin for async and clarity

Refactor BankService to separate account and transaction logic:
- Rename `GetTransactions` to `GetAccounts` and update functionality.
- Update `InvokeBank` to call new `GetAllAccounts` method.
- Enhance `GetAccountDetailsV2` to handle balances and transactions.
- Add helper methods: `GetAllAccounts`, `GetAccountById`, `ListTransactionsForAccount`.
- Update `MapToInternalV2` for additional account details.
- Modify `GetTransactionsForAccount` to use single `BankConfig`.
- Update `IBankService` interface for method changes.
- Improve logging with structured logging and named placeholders.
- Refactor `KARService` for structured logging and initialize cache.

Update Plugin for async processing and improved readability:
- Make `ProcessResponse` method asynchronous in `BankClient_v2.cs`.
- Simplify `ProcessResponse` in `Bankv2.cs`.
- Remove `SkipKAR` parameter in `Metadata.cs`.
- Introduce `IHttpClientFactory` in `Plugin.cs` and refactor methods.
- Rename `GetEndpoints` to `GetBankEndpoints`.
- Refactor `CreateBankConfigurations` for multiple configurations.
- Improve readability and logging in `ReadEndpointsAndCache`.
- Remove and redefine several methods with updated logic.
