Summary

Normalize table column identifiers before resolving ATTRIBUTE and TAG filters in DELETE predicates. This prevents mixed-case identifiers such as deviceId from producing unresolved filter symbols and a 301 NullPointerException.

Add regression coverage for ATTRIBUTE comparisons, NULL checks, LIKE, and IN with mixed-case identifiers, and strengthen the too-many-devices rejection test to verify data remains intact before a corrected narrower DELETE.

Validation

• Confirmed both regression cases fail on the base revision with the 301 NullPointerException.
• TableSimpleIT: 4 selected deletion tests passed, 0 failures, 0 errors, 0 skipped.
• TableClusterIT (1 ConfigNode, 3 DataNodes): 4 selected deletion tests passed, 0 failures, 0 errors, 0 skipped.
• Clean source reactor install for the required modules, Spotless apply, and integration-test selection check passed.
