feat(server): API de synchronisation incrémentale LWW (ticket #50)
Ajoute l'endpoint api/sync_api.dart, les use cases de synchronisation (application/sync_use_cases.dart) et l'adapter Postgres (infrastructure/postgres/synced_resource_repository.dart) implémentant un upsert LWW atomique via CTE (INSERT ... ON CONFLICT ... WHERE client_updated_at < EXCLUDED.client_updated_at, avec fallback UNION ALL pour le cas ignoré). dart pub get OK, dart analyze clean, dart test 15/15 vert. SQL d'upsert relu manuellement et jugé correct ; pas de test de bout en bout contre un vrai PostgreSQL faute d'accès Docker dans ce sandbox. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
