TED5000 Pro v0.2.0

Phantom (standby) load tracking.

• Records the lowest consumption during a configurable quiet window each night
• Rolling average across N nights (default 7, 1-90 configurable) with per-night history in attributes
• Monthly cost of that standby load at your current utility rate
• History persists across restarts; windows crossing midnight count as one night

Also in this release: line-to-line (~240 V) voltage sensors derived from the reported leg voltage, and the integration is now simply named TED5000 Pro.
