[kidinov]

Description

The PR sets maximum screen brightness when we show generated QR

Testing instructions

• Collect payment via scan to pay payment method
• Notice that the brightness goes maximum on that screen, and returns back when a user leaves/hides it

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
