Changed
- Energy history file format optimized: switched from pretty-printed array-of-objects to compact columnar JSON (object of arrays); key names appear once instead of per record; reduces file size by ~80% (e.g. 10 000 records: ~7 MB → ~1.3 MB); backward-compatible — existing files in old format are automatically migrated on first save; REST and MQTT output unchanged (still array-of-objects)
- All numeric values in energy history records rounded to 3 decimal places
