fix: Code Mod | Azure Template Validation & Deploy-Test-Cleanup Pipeline fix

[Vemarthula-Microsoft]

Purpose

• ...
  This pull request makes significant improvements to the GitHub Actions workflows for Azure deployment and testing. The main changes focus on more robust resource management during deployment and teardown, improved output handling, and better environment variable usage. The deployment workflow now ensures resources are properly purged after deletion, handles region selection dynamically, and improves reliability and error reporting.

Deployment Workflow Improvements

• Added dynamic region selection for AI deployments and propagated the selected region to downstream jobs, replacing hardcoded values. (.github/workflows/deploy.yml) [1] [2] [3]
• Improved resource deletion and purging logic: resource group deletion is now followed by polling for completion, and soft-deleted resources (OpenAI, KeyVaults, Log Analytics) are purged in dedicated, fault-tolerant steps. (.github/workflows/deploy.yml)
• Enhanced deployment output extraction by making the lookup for WEB_APP_URL case-insensitive and adding troubleshooting output if the value is missing. (.github/workflows/deploy.yml)

Resource Management and Error Handling

• Refactored resource identifier collection and purging steps to be more robust against missing resources and errors, using best-effort logic and clearer messaging. (.github/workflows/deploy.yml) [1] [2]
• Added a final, idempotent resource group deletion step to ensure complete cleanup. (.github/workflows/deploy.yml)

Test Workflow Improvements

• Updated backend test skipping logic to use step outputs instead of environment variables, improving reliability and clarity. (.github/workflows/test.yml)

Other Minor Changes

• Changed the environment for template validation from production to dev and pinned the Azure template validation action to a specific version for stability. (.github/workflows/azure-dev-validation.yml)

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.
