feat(sirius-x): prices in BCH, amounts in bits, live BCH/USD rate from several exchanges

Every dollar figure on the site came from a hard-coded 250,000 sats per dollar, which implies $400 per BCH; the market is near $250, so name prices, TLD fees and sale listings were shown about 60% too cheap in dollars. The gateway now serves /api/price: the median of Coinbase, Kraken, Bitstamp, Binance and CoinGecko public tickers, no keys, cached 60 s, last good answer kept if every source fails. The site reads it first, queries the same tickers itself if the gateway is unreachable, remembers the last rate per browser, and only falls back to a constant for the very first paint. Pages repaint when the rate arrives, and the rate line says where it came from and how old it is. Units: satoshi no longer appear anywhere. Sale prices, the seller's input and the buy dialog are in BCH with the dollar figure beside them; balances, fees and dust are in bits (1 bit = 100 satoshi).
