Add three Chiller 9 sample datasets under src/couchdb/sample_data/tsfm: chiller9_annotated_small_test.csv (annotated test set), chiller9_finetuning_small.csv (finetuning dataset with segment_id), and chiller9_tsad.csv (time-series data for anomaly detection). These files provide small sample data for testing and training TSFM/TSAD workflows.

Pull request overview
Adds a new TSFM (Time Series Foundation Model) sample dataset for “Chiller 9” under src/couchdb/sample_data/tsfm/, providing both raw CSVs and IoT-style JSON equivalents intended for forecasting, fine-tuning, and anomaly-detection workflows.
Changes:
- Added three TSFM CSV datasets (
tsad,finetuning_small,annotated_small_test) for Chiller 9. - Added three JSON versions of the same datasets with
asset_id+ timestamped sensor fields. - Introduced an annotated small test dataset that includes additional sensor fields (e.g., Schedule, Liquid Refrigerant Evaporator Temperature).
