Camera does not resume after scanning QR code

[chetanr25]

Description

After scanning a QR code and displaying the scanned text, the camera preview gets paused. Even after performing an action such as tapping OK or Copy text, the camera does not resume automatically. The camera only becomes active again after manually tapping the refresh button in the app bar.

This breaks the expected scanning flow and forces the user to refresh the camera every time a QR code is scanned.

Steps to Reproduce

1. Open the QR scanner screen.
2. Scan any QR code.
3. Wait for the scanned text dialog to appear.
4. Tap OK or Copy text.
5. Observe that the camera preview remains frozen.

Expected Behavior

After closing the scanned text dialog, the camera should automatically resume and be ready to scan the next QR code without any manual refresh.

Actual Behavior

The camera preview remains paused and only resumes when the user manually taps the refresh button in the app bar.

Acceptance Criteria

• Camera automatically resumes after the scan dialog is dismissed.
• No manual refresh should be required to continue scanning.
• Scanning flow should feel seamless for consecutive scans.
