Challenge: Diagnose, fix and continuously watch the MySQL path

تحدّي: شخّص وصلّح وراقب طريق الـ MySQL على طول

The web tier ( web1 ) cannot reach the MySQL server db1 on TCP 3306 in ch-nw-vnet . Use Network Watcher to prove the cause before changing anything, apply the narrowest fix (only the web subnet may reach MySQL), prove it end to end and make sure the next regression raises an alert.
