fix: improve CHECK constraint and nested SELECT indentation

- Spawn context with increased indentLevel for CHECK constraint expressions
- Spawn context with increased indentLevel for nested SELECT statements
- Update snapshots to reflect proper indentation of logical scopes
- Ensure tax_rate expressions in CHECK constraints are properly indented
- Ensure nested SELECT FROM clauses are properly indented within subqueries
