v3.2.20

Fixed

• Starting charging now works when the charger is schedule / Eco-Smart paused. A bare start left the schedule-override flag set, so the charger re-paused itself within ~10 s (the charging switch appeared to "flap" off). Now a start while paused also clears the override, so "turn charging on" actually charges — the same start-then-Resume pairing users did by hand. A normal (not-paused) start is unchanged.
• Resume Schedule is now idempotent. It sent a defensive Stop before clearing the override; if an automation re-affirmed an already-charging session (e.g. every 15 minutes on a price refresh) that Stop interrupted charging for ~10 s. Resume now no-ops when nothing is actually paused, so redundant presses are harmless.

Both apply to the HTTP/integration and MQTT command paths. Thanks to @ollitaipale-cyber for the detailed analysis (#47).
