[Feature Request]: Enable users to copy a connection URL to the database

@Benjin is already working on this.

Since Jan 27, 2026.

### Feature Description

Currently, users can share MSSQL database connection details by manually copying the connection string. However, there is no built-in UI feature in VSCode that allows users to generate and share a URI for this purpose. This request proposes adding a native option in the MSSQL extension UI to generate a URI that, when opened, launches VSCode and connects to the specified database.

Benefits:
- Streamlines collaboration by simplifying connection sharing.
- Reduces manual errors from copying connection strings.
- Aligns with existing URI-based workflows (e.g., Kusto).

### Problem and Motivation

A user wants to share a database connection with a colleague. Instead of copying and pasting the connection string, the user should be able to generate a URI like:
vscode://ms-mssql.mssql/connect?server=&database=&user=

Opening this URI should automatically launch VSCode with the MSSQL extension and connect using the provided parameters.
