Cumulates all the v1.8.4 data fixes (solar #215/#220, grid #200, battery #216, display radius #197) plus a cleanup pass.
What's new since beta.3
Dead-code cleanup now that every measured series reads the recorder change metric:
- Removed the PV rolling sample buffer, the 5-minute trainer LTS slot + its cache + fetch, and the
fetchPvStatisticsrole switch (calibration-only now). _pvHistoryand_batteryPowerHistorykept (still feed calibration, the day-strip integration, the per-entity tooltip and the radial battery track).
Data-interval control reframed from "Update frequency" to "Graph detail": it no longer changes the data (always HA's 5-minute statistics now), only how densely the curve is drawn, so it reads as a perf / smoothing lever next to the display radius. Range 1-12, default 4 (15 min). EN + FR.
Test focus is unchanged from beta.3: compare solar / grid / battery against the HA Energy dashboard, and check the display-radius perf lever on older phones.
