Two correctness fixes to the wealth dashboard, found while validating
contribution data against actual-viktor (source of truth):
1. dav_corrected (Fix 1): LOCF gap-fill scoped to the Fidelity pension.
A PlanViewer scrape gap left total_value=0 for 13 days from 2026-02-16,
which cratered net worth and produced a phantom -£97,457 "contribution"
in Feb then +£100,458 in Mar. Carry the last non-zero day forward across
the gap (a £0 pension valuation is always a scrape gap, never real).
2. wealth.json (Fix 3): "Monthly contributions vs market gain" and "Annual
change decomposition" now use consecutive period-end deltas instead of
within-period first-to-last-obs, so contributions landing near a period
boundary are no longer dropped/mis-attributed.
Verified live: Feb-2026 monthly contribution now +£34,000 (real Trading212
RSU-proceeds investment, reconciles with actual-viktor), no spurious
negatives. Brokerage contributions unchanged (already correct).
Applied via scripts/tg (wealthfolio + targeted monitoring ConfigMap).
