Adds the analytics half of the CoinMarketCap reference: a value-over-time chart (GET /crypto/history, forward-filled from AssetValuation like Net Worth's own series but scoped to crypto assets), an allocation breakdown by coin, and stat tiles for all-time profit, total invested (cost basis), and best/worst performer. Deliberately no "24h" range — history is only as dense as the sync cadence (button or once/day), so a 24h chart would be one or two points, not a smooth intraday line. Cost basis / all-time profit / best-worst performer aren't separate endpoints: they're trivial to derive client-side from fields already in GET /crypto/holdings, so no redundant backend logic. Allocation card follows the dataviz skill's categorical rule: top 7 coins by value get a fixed-order color from the app's already-validated 8-slot ramp, an 8th+ folds into "Other" rather than generating a new hue. 82/82 backend tests passing (3 new for /crypto/history). Verified live against the real CoinGecko API — and caught a real holding the user had already added directly through the UI between messages, which the smoke test correctly left untouched while cleaning up only its own test data.
