cs-prices: full ByMykel catalog, every config, daily multi-source prices, item pages with working charts

- cs.skins catalog (weapons, knives, gloves, stickers, cases, agents, charms, …) refreshed weekly
- every market config: wears in float range, StatTrak, Souvenir, Doppler/Gamma phases
- cs.daily_prices (one row per config/stream/day, idempotent) from Skinport, Steam, CSFloat, Buff163
- cs.price_windows for 24h/7d/30d/90d sale aggregates, cs.fx_rates (ECB)
- scripts/cs-prices.ts daily|catalog|prices; legacy ingest fixed for the new unique index
- skin browser + /projects/cs-prices/[slug] with variant/wear/phase switcher and real charts
- charts show points for short histories and pad sparse time axes
