- Refactor #fetchExchangeRatesWithFallback into smaller helper methods: - #fetchRatesFromPriceApi: handles primary Price API call - #fetchRatesFromTokenPricesService: handles fallback fetching - #createNullRatesForCurrencies: creates null entries for failed currencies - Rename private members to use hash syntax (fixing lint errors) - Add partial success handling: when some currencies succeed and others fail, only failed currencies trigger fallback - Add comprehensive tests for partial success scenarios - Update existing tests to match new expected behavior

Compare
…nd failedCurrencies
- Updated #fetchRatesFromTokenPricesService to return { rates, failedCurrencies }
similar to #fetchRatesFromPriceApi for consistency
- Removed null currency creation from fallback method - failures now add to
failedCurrencies instead of creating null rates inline
- Step 4 now takes the final list of failed currencies from step 3 to build
null rates, simplifying the logic
- Simplified #createNullRatesForCurrencies to only take currencies array
- Renamed PriceApiResult type to FetchRatesResult for broader applicability
- Wrapped the entire method body in try-catch so it never throws - On any unexpected error, returns all currencies as failed - Updated JSDoc to document that the method is designed to never throw - This allows #fetchExchangeRatesWithFallback to use const instead of let and removes the external try-catch, simplifying the orchestration logic

Explanation
Modifies CurrencyRateController to better handle fallback currency rates
Also decoupled the complex currency fetching logic into separate methods for the main exchange rates fetch vs spot prices fetch.
Oh and also resolve ESLint issues (agent led this)
