refactor(ai): enhance AI trace integration and OCR normalization

- Add FlyerTraceSupplement type for AI trace metadata
- Implement getFlyerTraceSupplements method to fetch trace supplements
- Update AiTraceService to include prompt/rawOutput and counters in flyer traces
- Add persistFlyerTrace method to FlyerImportService for trace persistence
- Enhance AiFlyerParserService to return structured trace data with prompts and retries
- Update FlyerNormalizerService with OCR typo fixes for cheese variants and spröd bakad firre
- Improve Flutter admin panel with selectable text, warnings display, and tooltips
- Add comprehensive tests for AI trace supplements and normalization rules
