Viktor Barzin 51456a96f6 fan-control: estimate + expose fan power (fan_watts_est) 
The iDRAC reports only total DCMI watts + RPM (no per-fan power), so add a
cube-law fan-power estimate: fan_W ~= 0.0205*(RPM/1000)^3, calibrated to the
2026-06-05 sweep (fits within ~3W; ~2W floor -> ~99W full). The daemon reads
live RPM each loop and pushes pve_fan_control_fan_rpm + _fan_watts_est.
Surfaced in HA as sensor.r730_fan_power_est + a "Fan Power (est)" card on the
dashboard-it Server view, next to total power. 46 bash tests green; verified
live (9120rpm -> ~15W est).
