This PR introduces an aggregation method dropdown for the Big Number with
Trendline visualization.
It allows users to apply different aggregation functions (SUM, AVG, MIN,
MAX, MEDIAN, LAST_VALUE) to the selected metric.
-->
### **SUMMARY**
This PR enhances the **Big Number with Trendline** visualization by
introducing an **Aggregation Method** dropdown.
Previously, the chart defaulted to the **last value**.
With this change, users can now apply different aggregation methods to their
selected metric, such as **SUM, AVG, MIN, MAX, MEDIAN, and LAST_VALUE**.
### **BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF**
<!--- Include screenshots or a GIF demonstrating the feature if applicable.

### **TESTING INSTRUCTIONS**
To manually verify this feature:
1. Navigate to **Charts** and select a chart using **Big Number with
Trendline** as the visualization type.
2. Select a **Temporal X-Axis** and a **Metric** for the query and run.
3. Choose different values from the **Aggregation Method** dropdown and
observe updates in the **Big Number**:
- **SUM** → Displays the total of all values over the selected period.
- **AVG** → Displays the mean (average) of all values.
- **MIN/MAX** → Displays the lowest/highest value in the selected range.
- **MEDIAN** → Displays the middle value, reducing the effect of
outliers.
- **LAST_VALUE** → Works as before, displaying only the most recent data
point.
