Draft: Implement action buttons section for workspace details page

MR: Pending

Description

As part of our new designs for Workspaces, we need to add an action buttons section to the workspace details page so that users can quickly perform common workspace actions directly from the details view.

Visual Changes

Acceptance criteria

• Add "Open in VS Code" button
• Add "SSH" button that provides SSH connection details or initiates SSH connection
• Add "Open workspace" button that opens the workspace environment in new tab
• Add "Download logs" button that downloads workspace logs as a file
• Proper error handling for failed actions
