fix: update indexing service fingerprint constants and nightly fmt

Adding ParquetMergePolicyConfig and ParquetIndexingConfig to
IndexingSettings changes the Hash output, which changes the pipeline
params fingerprints. Updated the hardcoded test constants.

Added a comment explaining how to recompute them when IndexingSettings
fields change.
