Subject: [PATCH] Add Microsoft SQL Server (MSSQL) database support

- Add custom Rust backend using tiberius crate for MSSQL connections
- Implement mssql_connect, mssql_disconnect, mssql_query, mssql_execute commands
- Add MssqlAdapter with SQL Server-specific schema queries
- Support SQL Server pagination (OFFSET FETCH syntax)
- Handle MSSQL-specific identifier quoting with square brackets
- Integrate with existing connection manager, query execution, and schema tabs
- Support SSH tunneling for MSSQL connections
