## Summary by CodeRabbit

* **Bug Fixes**
* Improved chart tooltip date label formatting: tooltips now detect
ISO-like date strings and format them consistently, while preserving
previous formatting for other values. This change ensures correct,
readable dates in both bar and line chart tooltips within reports.
