Format SQL output

Add a static flag to enable SQL formatting for SQL Server models and apply SqlFormatter to query SQL before returning it. Update verified SQL fixtures to match the new formatted output (lowercase keywords, no brackets, aligned columns). This ensures consistent, readable SQL output for EF query tests.
