Michiel Berger e39f78fcc5 Fix two timeline bugs 
1. /api/timeline silently defaulted missing export_rate to None → 0,
   which broke the LP for dad's terugleveringskosten scenario. With
   export=0, charging during surplus has no benefit, so the battery
   stayed half-empty while solar exported. Fix: when the param is
   absent, fall back to DEFAULTS['export_rate'] (matches the form's
   initial value). Explicit blank still means 'use saldering toggle'.

2. uPlot charts had legend disabled. Re-enabled with per-series value
   formatters so hovering shows '14:00 NL · −1.70 kWh/h' style values.

Backtest the actual ROI of a home battery against real historical electricity prices and solar irradiance.

Answers: "If I had owned this battery (plug-in or installed) over the last N years, what would it have actually saved me?"
