Subject: [PATCH] fix(build): ensure fresh Flutter build on each deploy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add flutter clean before build to prevent stale cached artifacts
- Add VERSION build arg for explicit cache busting
- Reorder build steps: clean → pub get → build_runner → health.json → build
- Replace deprecated dart:html with package:web in iframe_view_web.dart
- Add lint ignore to generate_health_json.dart

Fixes issue where Docker layer caching kept old main.dart.js
while regenerating health.json with new version number.
