feat(ai): enhance AI trace warnings with product context

- Added `productName` field to `AdminAiWarning` to include product context in warnings
- Updated `collectWarnings` to extract and include `rawName` as `productName` in AI trace warnings
- Added `signals` field to `FlyerParseItem` type for detailed product signals
- Enhanced Flutter admin panel to display product names in AI trace warnings
- Added new `AdminAiTraceResponse` DTO for AI trace data structure
