Make the setup-state push report whether it worked

It was documented 'Always returns 0', so the offboard's new 'Phase flags pushed' check was testing a constant and ticking regardless.

 # platform_push_setup_state
 #   Pushes the Varaverk wizard setup state to all partners via the WebGUI PHP API.
-#   No-op if php is unavailable. Always returns 0.
+#   Returns 1 if any partner did not take it, 0 otherwise. No-op returning 0 if php is absent.

+#   This used to end with a bare `return 0` under the comment "Always returns 0", which meant
+#   every caller that wrote `platform_push_setup_state || X=false` was testing a constant.
+#   Wiring a failure branch onto a helper that cannot fail is worse than hardcoding the tick,
+#   because the code reads as though it checked.
