Rewrite OcrService to match the actual inference API response format (nested status/result structure with PascalCase/snake_case field names). Register IOcrService in DI with typed HttpClient and Polly v8 resilience (retry, timeout, circuit breaker via AddStandardResilienceHandler). Key changes: - Fix response model to match real API (InferenceApiResponse) - Map correct field names (InvoiceNumber, InvoiceDueDate, OCR, Amount, etc.) - Add extract_line_items=true for VAT summary extraction - Copy stream before sending to avoid disposal conflicts with retries - Add JsonException handling for malformed responses - Remove sensitive data from error logs - Add 35 unit tests covering field mapping, VAT parsing, error handling, decimal/date formats, and content type detection
