[Refactor]: add api clients and refactor components

[DanielMicrosoft]

Current issues:

• Don't get error pop-ups (ie from VM module commands missing).
• Standardize service layer naming conventions.

Pull Request Overview

This refactor adds centralized API client services and standardizes error handling across the workspace editor components. The changes replace direct axios calls with dedicated service layers for improved maintainability and consistency.

Key changes:

• Introduced structured API clients (workspaceApi, specsApi, commandApi, cliApi, errorHandlerApi) to centralize HTTP communication
• Standardized error handling with a unified errorHandlerApi.getErrorMessage() method
• Converted multiple components from direct axios usage to service-based API calls
