Michiel Berger ab4f9712b5 Default export_rate to 0; add tie-breaker so battery fills before exporting 
- DEFAULTS['export_rate'] = 0 (terugleveringskosten can be re-enabled per
  scenario via the Advanced field — keeping the headline default simple).
- LP gets a microscopic per-hour penalty (1e-6 € · hour) on charging that
  prefers earlier hours, and on discharging that prefers later. Total
  effect on annual savings: < €0.001 (well below display rounding). But
  visually the battery now fills as soon as surplus arrives, instead of
  the LP arbitrarily mixing surplus hours with grid-arbitrage hours when
  both give the same daily total.

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?"
