ci: run full Azure integration suite under OIDC

With provider pins modernized (prior commits), all examples in
examples/azure/ are on AzureRM >= 3.x and OIDC-compatible. The Azure
integration workflow no longer needs the -run filter that scoped it
to two AzureRM 3.x-ready tests, addressing the fragile-enumeration
feedback on #1794:
#1794 (comment)

Also flips concurrency.cancel-in-progress to false so a cancelled run
can't orphan Azure resources mid `terraform apply`.
