[ psic4t/nospeak ] fix(android): prevent battery drain by avoiding connection restarts on energy profile changes Energy profile changes (screen on/off, charging) were triggering full WebSocket connection restarts with TLS handshakes, which caused worse battery drain than the previous fixed 30-second ping implementation. Changes: - Remove startRelayConnections() call from evaluateAndApplyEnergyProfile() - Energy profile changes now apply lazily: rebuild OkHttpClient with new ping interval, but keep existing connections active
