Remove Unnecessary Empty Space at Bottom of Voucher Screen for Improved Layout

Is your feature request related to a problem? Please describe.
There is noticeable empty space at the bottom of the voucher screen, which affects the visual balance and user experience. It feels like the screen layout is incomplete or misaligned.

Describe the solution you'd like
I would like the layout of the voucher screen to be adjusted so that the empty space at the bottom is eliminated or utilized effectively, making the design more polished and consistent with the rest of the app.

Describe alternatives you've considered

Reducing the padding or margin at the bottom of the screen.

Adjusting the layout to stretch the content appropriately.

Adding a footer element (e.g., app tips, FAQs, or terms related to voucher usage) to use the space constructively.

Additional context

The issue identifies only the voucher screen and names no file, test, or entry point. Locate the voucher screen's layout, inspect how its bottom spacing is produced, and compare it with the app's other screens. Done means the unnecessary empty space is removed or intentionally used without harming the screen's visual balance.
