[FEATURE REQUEST] - Add Arrow Key Navigation for Name Input Field

Your issue description is well-written, but here’s a refined version to improve clarity and address potential future uses:

Currently, the name input field does not allow players to use the left and right arrow keys to navigate within the text. This limitation is frustrating as it forces users to delete all letters after a mistake to correct it, as they cannot move the cursor backward or forward.

This enhancement adds arrow key functionality, allowing players to navigate within the text field to edit specific characters more easily. This change significantly improves the user experience for name entry and can also be extended to other text entry fields added in the future.
