Widget Configurable Time frame in full screen

### Problem Statement

Allow modification to the selected time frame using the standard date‑picker options (last day, last 7 days, etc.). Right now the only way to change the time frame is to click and drag within the graph.

### Solution Brainstorm

_No response_

### Product Area

Dashboards

Start by locating the dashboard widget's fullscreen entry point and the existing standard date-picker implementation. Confirm that presets such as last day and last 7 days can change the selected timeframe while the widget remains in fullscreen mode.
