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

Start by locating the voucher screen and inspecting its layout, especially the bottom spacing and current padding or margins. The work is done when the screen no longer has noticeable empty space and its visual balance is consistent with the rest of the app; verify the result on the voucher screen.
