[Copilot]

Pull request overview

Adds a GitHub Copilot Chat recovery path from Schema Designer’s publish dialog when publish/report errors occur, by surfacing an “Ask GitHub Copilot to Fix” action and passing error context as a prompt override into the existing mssql.openCopilotChatFromUi command.

Changes:

• Adds a new publish-dialog error-state button that opens Copilot Chat with a generated prompt containing the current error details.
• Extends CopilotChat.OpenFromUiArgs / openCopilotChatFromUi to accept an optional prompt override.
• Adds unit tests for the new prompt-building helpers, button behavior, and main controller prompt override handling.
