Subject: [PATCH] fix(custom/graph): guard signal config with isInt() to avoid
 SIGABRT

refresh() called config_["signal"].asInt() unconditionally on every RT
signal; a non-integer "signal" value throws Json::LogicError and aborts
Waybar. Matches the guard already present in custom/image/idle_inhibitor.
Fixes #3514.
