Follows lib/esp32-lua-api: gui -> screen, node -> tree, settings and input split into screen/sys/touch/buttons. Settings is one provider lighter, with timezone on Sys and rotation and theme on Gui, which now applies and persists a rotation in one call. The calibration screen stashes the rotation it borrows rather than relying on a transient setter.
