Refactor DeviceService and improve test reliability

- Removed unnecessary code in `DeviceService`
- Increased delay in `MdnsChromecastLocatorTester` for event capture from 5100ms to 5200ms.
- Updated `TestNewProgressiveDiscovery` to assert at least 3 discovered Chromecast devices.
- Added application stop call in `MediaChannelTester` and reduced wait time for application pause check to 300ms.
- Added `ConfigureAwait(false)` in `ChromeCastClient` for improved async performance.
