Fix JOIN formatting spacing issue - eliminate trailing spaces after table aliases

- Fixed JoinExpr method to properly handle spaces in pretty formatting mode
- Added leading space to ON and USING clauses to maintain proper SQL syntax
- Updated snapshots to reflect improved formatting that matches Dan's requirements
- All tests passing with enhanced JOIN, CREATE POLICY, and CTE formatting
