refactor(cli): compress build_*_item with prompt_or_flag

Plan B Phase 3 sub-step 2. Replaces the
title.map(Ok).unwrap_or_else(|| prompt("Title"))? chain in all
seven build_*_item functions with prompt_or_flag, and folds
login's or_else(|| prompt_optional(...).ok().flatten()) for
username and url into prompt_or_flag_optional. prompt_secret
sites and the parse-on-Some-only patterns (expiry, dob, card
kind, totp algorithm) stay as-is per spec. Removes the
#[allow(dead_code)] attributes from the four helpers in
prompt.rs now that callers exist.
