Fix inconsistent number ranges for EFTPOS pin & access code (#6050)

# About the pull request

This PR fixes a couple places where tgui_input_number is called with
default arguments when it should be within a specific range for the
EFTPOS when specifying the access code and pin.

# Explain why it's good for the game

Certain values can currently lock you out of using the EFTPOS.
