fix: Replace deprecated WindowManager display APIs and add HDR capabilities

- Replace WindowManager.defaultDisplay with DisplayManager.getDisplay()
  which is the recommended approach on API 30+
- Use Display.mode.refreshRate on API 30+ for accurate refresh rate
- Add HDR capability collection using Display.HdrCapabilities on API 24+
- Return fallback DisplayInfo if DisplayManager is unavailable
- Remove unused WindowManager import
