[!NOTE] Adds new Asset Picker Opened and Asset Selected metrics events and wires them into the bridge controller analytics pipeline.

• Metrics/Telemetry:
  • Add new events in utils/metrics/constants.ts: AssetPickerOpened, AssetSelected.
  • Extend RequiredEventContextFromClient in utils/metrics/types.ts with payloads for the new events and include them in EventPropertiesFromControllerState.
• Bridge Controller (bridge-controller.ts):
  • Handle AssetPickerOpened and AssetSelected in #getEventProperties, returning base properties only.
