v0.9.0 — Financial rebuilt around bars

Three same-weight tables of right-aligned figures could not show the thing that matters: that €1.59 went into the battery to bring €1.67 back. Rows now carry a proportional bar as well as a number.

• How the saving is made — each contribution scaled against the largest, green for what came back, red for what went in, net emphasised beneath a rule.
• By tariff period — diverging bars around a centre line. Spend runs left, return runs right, so the arbitrage reads at a glance where four columns of near-identical figures did not.

Duplication removed. "Solar value" and "Avoided by solar" were the same number under two names, and battery charge cost appeared in both blocks. The Saving and Arbitrage columns differed only by solar, so three of four rows printed the same figure twice.

Negative amounts were rendering as €-1.59. The sign now sits outside the symbol and uses a true minus (−), which aligns with tabular figures where a hyphen does not.
