fix: Support both uppercase and lowercase table names in TABLE_CONFIGS

- TABLE_CONFIGS now accepts both 'RAWDATACOR' and 'rawdatacor' as keys
- TABLE_CONFIGS now accepts both 'ELABDATADISP' and 'elabdatadisp' as keys
- Reuse same config dict for both cases to avoid duplication

This allows FullMigrator to work correctly when initialized with
uppercase table names from the CLI while DataTransformer works
with lowercase names.

Fixes: 'Unknown table: RAWDATACOR' error during migration
