The Finanzen slide crashed on mount with "a.toFixed is not a function".
Traced to UnitEconomicsCards.tsx:59 calling ltvCacRatio.toFixed(1),
where ltvCacRatio arrives as a string.
Root cause: the cached path in /api/financial-model/compute returns raw
rows from pitch_fm_results. node-postgres returns NUMERIC / DECIMAL
columns as strings by default, so lastResult.ltv_cac_ratio (and every
other *_eur / *_pct / *_ratio field) flows through the app as a string.
Arithmetic-heavy code paths survived on accidental string-coerce (`-`,
`/`, `*`), but direct method calls like .toFixed() don't coerce, which
is why Unit Economics was the visible crash site.
Fix at the boundary: register a single types.setTypeParser(NUMERIC, …)
on the pg Pool so every query returns real numbers. All our NUMERIC
values fit well inside Number.MAX_SAFE_INTEGER, so parseFloat is safe.
One-line change, no component-level defensive coercions needed.
