Fix Checkstyle violations in AbstractTestDistributedQueries.java

- Fix left brace placement for testViewWithUUID, testExplainAnalyzeWithCTEMaterialization, and assertExplainAnalyze methods
- Split long lines to comply with 80-character limit
- Add proper Javadoc comments
- Remove trailing whitespace
