   We generally require a GitHub issue to be filed for all bug fixes and 
enhancements and this helps us generate change logs for our releases. You can

   - Closes #19786
   
   ## Rationale for this change
   
   <!--
    Why are you proposing this change? If this is already explained clearly in 
the issue then this section is not needed.
    Explaining clearly why changes are proposed helps reviewers understand your 
changes and offer better suggestions for fixes.  
   -->
   This PR consolidates the small test file `cte_quoted_reference.slt` into the 
main `cte.slt` file as requested in issue #19786. The separate file was small 
enough that it didn't need to be maintained independently, and consolidating it 
improves code organization and maintainability.
   
   ## What changes are included in this PR?
   
   <!--
   There is no need to duplicate the description in the issue here but it is 
sometimes worth providing a summary of the individual changes in this PR.
   -->
   - Merged CTE reference resolution tests from `cte_quoted_reference.slt` into 
`cte.slt`
   - Added `CREATE TABLE orders AS VALUES (1), (2);` statement to support the 
merged tests
   - Fixed 3 pre-existing case-sensitivity bugs by changing `WHERE N < 10` to 
`WHERE n < 10` in recursive CTE tests
   - Deleted `cte_quoted_reference.slt` as it's now consolidated into the main 
file
   
   ## Are these changes tested?
   
   <!--
   We typically require tests for all PRs in order to:
   1. Prevent the code from being accidentally broken by subsequent changes
   2. Serve as another way to document the expected behavior of the code
   
   If tests are not included in your PR, please explain why (for example, are 
they covered by existing tests)?
   -->
   
   Yes, all changes are tested:
   - The consolidated tests from `cte_quoted_reference.slt` are now part of the 
`cte.slt` test suite
   - All sqllogictest tests pass successfully: `cargo test --test sqllogictests 
-- cte`
   - The case-sensitivity fixes ensure that field references match their 
definitions (lowercase `n`)
   
   
   ## Are there any user-facing changes?
   
   <!--
   If there are user-facing changes then we may require documentation to be 
updated before approving the PR.
   -->
   No, there are no user-facing changes. This is purely a test file 
reorganization that improves code maintainability without affecting 
DataFusion's functionality or API.
   
   
   <!--
   If there are any breaking changes to public APIs, please add the `api 
change` label.
