feat: Dual camera recording with front and rear cameras

[torturado]

This update adds the ability to record simultaneously with both front and rear cameras. Users could now toggle between single and dual camera modes.

Changes:

• Mode Toggle: Added a button and supporting logic to switch between single and dual camera recording modes.
• Dual Camera Functionality: Implemented dual camera management to handle recording from both cameras at the same time.
• Temporary UI Adjustment: Camera previews have been temporarily removed until a layout for displaying both camera feeds is finalized.

Testing:

• Devices Tested: Android Studio emulator (API 34) and a real Google Pixel 8 Pro.
• Features Confirmed: Verified successful simultaneous recording and correct storage of dual-camera videos.
