Pull request overview

This PR aims to fix two SolaX Cloud integration issues: (1) scheduled charge/export windows that span midnight not being applied correctly, and (2) incorrect/absent load power reporting by introducing a dedicated load_power sensor derived from inverter + battery + grid telemetry.

Changes:

• Updated apply_controls() to better detect charge/export windows that span midnight.
• Added per-plant load_power publishing and wired automatic_config() to reference it (plus set battery_power_invert and fix battery_rate_max arg name).
• Extended SolaX tests to cover midnight-spanning windows and load power calculation; updated cspell dictionary entries.

• publish_device_realtime_data() logs the full real-time payload for every device on every publish cycle. Since this runs regularly (e.g., once per minute) this can spam logs and leak large payloads into HA/AppDaemon logs. Please guard this behind a debug flag / log-level check, or remove it (keeping only concise summaries when needed).
