Pull Request Overview

This PR adds comprehensive support for Data-Tier Application operations (import/export/deploy/extract dacpac and bacpac files), replicating functionality previously available in Azure Data Studio. The feature enables users to launch these operations from the Object Explorer or command palette through a webview interface that guides them through selecting the operation type, server connection, database, and file paths.

Key Changes:

• New webview-based UI for managing dacpac/bacpac operations
• Command registration for all four operation types (deploy, extract, import, export)
• Validation logic for file paths, database names, and connections
• Support for both new and existing database deployments with confirmation dialogs
