[I] Add fallback coverage for unsupported Paimon scan data type [auron]

["weimingdiit (via GitHub)" <gi...@apache.org>]

URL: https://github.com/apache/auron/issues/2449

   **Is your feature request related to a problem? Please describe?**
   
   Paimon native scan rejects columns whose data types are not supported by Auron.
   The fallback path is implemented, but the current integration suite does not verify
   that unsupported scan data types remain on Spark execution.
   
   Without this coverage, future changes to Paimon scan conversion could accidentally
   allow unsupported types into the native path.
   
   **Describe the solution you'd like**
   
   Add integration coverage for a Paimon table containing an unsupported decimal type.
   The test should verify that:
   
   - Spark still returns the correct result.
   - The query falls back from `NativePaimonV2TableScan`.
   
   **Describe alternatives you've considered**
   
   No execution logic changes are proposed. This change only adds regression coverage
   for the existing fallback behavior.
   
   **Additional context**
   
   The test uses `decimal(38,10)`, which is outside Auron's currently supported native
   decimal range.
