ci: run full Azure integration suite under OIDC

With provider pins modernized in the prior commits, the Azure
integration workflow can run the full test/azure/... suite under OIDC
auth. Removes the brittle enumerated -run regex flagged in #1794
review feedback:
#1794 (comment)

Also:
- Flips concurrency.cancel-in-progress to false so a cancelled run
  can't orphan Azure resources mid `terraform apply`.
- Bumps go test -timeout from 45m to 120m and job timeout-minutes from
  60 to 150; the full sequential (-p 1) suite of ~28 tests can take
  60-90 minutes (heavier services like AKS/Synapse/SQL MI/MySQL
  flexible-server provision in 10+ minutes each).
