v1.7.1

✨ Added

• "Today" date-range preset, on every tab — a genuine calendar-day-so-far view (midnight to now), not the trailing 24h window "1d" gives you. Positioned leftmost, ahead of "1d".

🐛 Fixed

• Today's solar/self-sufficiency figures are now clearly labeled as a projection, not an actual. Solar isn't metered in the common case (most inverters aren't reachable locally), so it's modeled from a seasonal yield curve — a model with no concept of elapsed time, so it always returns a full day's total regardless of what time it actually is. Selecting "Today" early in the day was showing the whole day's projected solar output as if already produced. The Overview flow diagram and the Self-Sufficiency tab now show a clear note whenever the selected range includes today.
