Subject: [PATCH 1/6] Handle Azure Blob Storage paths in directory and file
 path evaluators: - Update `FormatDirectoryPathEvaluator` and
 `FormatFilePathEvaluator` to detect Azure paths (scheme == 'az'). - Skip
 directory/file checks for Azure paths, since Azure Blob Storage does not have
 true directories. - This prevents false validation failures for Azure storage
 paths.

Subject: [PATCH 3/6] Handle missing nf-azure plugin gracefully in path
 validation

- Update evaluators to check for Azure paths early using value.startsWith('az://')
- Skip validation for Azure paths when nf-azure plugin is missing
- Add comprehensive tests for Azure path validation
- Ensure non-Azure cloud paths (S3, GCS) are still validated normally

This allows pipelines using Azure storage paths to pass validation even when
the nf-azure plugin is not available in the test environment.

Subject: [PATCH 4/6] Remove Azure plugin check bypass for directory and file
 path evaluators

Previously, the validators for directory and file path formats would bypass validation and return success if the nf-azure plugin was missing and the path was an Azure path. This commit removes that bypass, so that missing plugin errors will now result in a validation failure, providing clearer feedback to users when the plugin is not installed or configured.
