Rename app crash to device crash

[LikeTheSalad]

Proposed commit message

Update crash event name from app.crash to device.crash in the Android OpenTelemetry dashboards.

WHAT: Updated ES|QL and KQL queries in the Application Overview dashboard to use device.crash instead of app.crash as the event name for crash events.

WHY: The EDOT Android SDK's crash events will be sent using the event name device.crash (aligning with OpenTelemetry Android). This change updates the dashboard queries to match the new event name so crash data is correctly displayed.
