Fixed unresolved references by matching the standard API client pattern:
- Changed from apiCall helper to try-catch pattern
- Use ApiClient.httpClient instead of direct httpClient reference
- Use ApiClient.getBaseUrl() instead of ApiConfig.baseUrl
- Added proper HttpClient parameter with default value
- Added proper error handling with response status checks
- Fixed verifyIOSReceipt to include transactionId parameter
- Fixed Android verification request format (use map instead of data class)
Now matches the pattern used by other API classes (ResidenceApi, TaskApi, etc.)
