Subject: [PATCH 1/2] Fix stale BTC price in /prices endpoints (#72)

The euroPrice cache (containing USD, EUR and BTC rates from CoinGecko)
had no TTL and only refreshed when blockchain blocks were detected.
If block detection stalled, the BTC rate could become hours stale,
causing significant mispricing on BTC-denominated trading pairs.

Add a 60-second TTL to euroPrice so it self-refreshes on endpoint
access regardless of block detection. Also fix the truthy check on
empty objects ({}) that prevented initial fetches.
