From 3a9325719a48d5af54e957c1b23b54279845f112 Mon Sep 17 00:00:00 2001 From: Ho Ngoc Hai Date: Thu, 16 Apr 2026 09:18:19 +0700 Subject: [PATCH] refactor(reports): consolidate duplicate PDF services into single implementations Remove duplicate minio-pdf-storage and puppeteer-pdf services, keeping the consolidated versions in pdf-generator.service.ts and pdf-storage.service.ts. Update reports module imports to use the correct classes.
