Subject: [PATCH] feat: add mode selector modal (Heat/Cool/Off) to classic Home
 screen

The thermostat had no way to actually set its operating mode: home_mode_label
was read-only, and no widget anywhere called climate.control with a mode.
Tapping the mode label now shows a modal (mirrors the existing
nav_menu_overlay pattern) with explicit Heat/Cool/Off choices.
