fix(ssl): prompt before setting IP cert path for panel

The IP certificate flow auto-set the panel cert path silently, unlike the
domain and Cloudflare flows which ask first. Add the same
"Would you like to set this certificate for the panel? (y/n)" prompt so
the IP flow is consistent and only configures the panel on confirmation.
