+Regression tests that every Azure resource class points at an icon that exists.

+``resource_classes/azure/databases.py`` declared ``resource_images/azure/database``
+while its icons ship under ``resource_images/azure/databases``, so 41 of its 45
+classes resolved to a missing file. Nothing warned about it: the alias resolved,
+so the renderer believed it had an icon and drew an empty node.
+
+``modules.drawing`` loads every module in the package into one namespace, so the
+alphabetically last module wins. That made ``databases.py`` override the working
+aliases in ``database.py``, and broke azurerm_redis_cache and
+azurerm_postgresql_flexible_server for anyone using them.

+- ``azurerm_static_site`` was renamed ``azurerm_static_web_app`` in the AzureRM
+  provider, and only the old name was aliased.
+- ``azurerm_cdn_frontdoor_*`` was never aliased, so ``FrontDoorAndCDNProfiles``
