console/prompt: use PromptInput in PromptConfirm method

[oooLowNeoNooo]

Problem

The PromptConfirm method was calling p.Prompt() directly, which bypasses the terminal mode management and unsupported terminal handling logic present in PromptInput. This could cause inconsistent behavior in unsupported terminals and improper terminal mode switching.

Solution

Changed PromptConfirm to use PromptInput() instead, ensuring it benefits from the same terminal mode management and fallback handling as other prompt methods.
