feat(flyer-import): integrate AI-based flyer parsing with image support

- Add support for PNG, JPEG, and WebP image formats in flyer import - Replace external importer service with internal AI-based parsing pipeline - Add new services: TextExtractorService, AiFlyerParserService, FlyerNormalizerService - Integrate Mistral AI, pdf-parse, and tesseract.js dependencies - Add quality confidence indicators and warning panels in Flutter UI - Update package.json with new dependencies and transform ignore patterns - Add documentation for flyer importer system - Add Kilo AI planning file for Happy Island project BREAKING CHANGE: Flyer import now uses internal AI parsing instead of external importer service
