[Tests] Add unit tests for storeTypeHandle and storeTypeLabel in store-type.ts

[gonzaloriestra]

WHY are these changes introduced?

The store helper functions storeTypeHandle and storeTypeLabel in packages/store/src/cli/services/store/store-type.ts lacked direct unit test coverage.

WHAT is this pull request doing?

Adds unit tests in packages/store/src/cli/services/store/store-type.test.ts covering:

• storeTypeHandle mapping development store types (APP_DEVELOPMENT, DEVELOPMENT, DEVELOPMENT_SUPERSET) to 'dev'
• storeTypeHandle mapping non-development store types (CLIENT_TRANSFER, COLLABORATOR, PRODUCTION)
• storeTypeHandle returning undefined for unrecognized store types and empty/null/undefined inputs
• storeTypeLabel returning title-cased labels for store handles
• storeTypeLabel returning empty strings for undefined or empty handle inputs
