fix: camera toggle along with flip

[santhoshvai]

💡 Overview

Bug on RN: use camera.flip() to move to rear camera then use camera.toggle() to switch it off, now toggle() it comes back as front camera, but the expectation is to see rear camera

📝 Implementation notes

Just deselect the device after applying constraints; the native side takes care of the device persistence.

Pull Request Overview

This PR fixes a bug in React Native where camera flip() followed by toggle() operations would incorrectly return to the front camera instead of maintaining the previously selected rear camera.

• Removes device direction state updates after applying constraints for camera flip
• Adds React Native-specific handling to prevent unnecessary track operations after device deselection
