Fix: Simplify input prompts in setup script

Reverts input functions to a simpler model by separating the
`echo` of the prompt from the `read` command itself.
This avoids using `read -p` with complex, colorized prompt strings,
which can sometimes cause issues in specific terminal emulators or
compatibility layers like those found in MobaXterm.

This change aims to improve robustness of input handling by:
1. Using `echo -e -n` for displaying the prompt with colors.
2. Using a plain `read` or `read -s` for capturing user input.

This is a further attempt to resolve issues where users might be
unable to type or paste into prompts within the MobaXterm environment.
