Release: develop -> main#111

updatePrices() fetched the tether/eur reference on every block tick, bypassing the existing 60s in-memory cache that getEuroPrice() and getDepsPrice() already respected. With block intervals of 6-12s this generated ~5-10x more upstream calls than the cache was designed to allow, exhausting the monthly CoinGecko quota. Route the call through refreshEuroPriceIfStale() so the same TTL applies to all entry points.
When fetchPrice() returns null/undefined (e.g. CoinGecko returns {}
for an unlisted collateral token), updatePrices() left the cache
entry untouched and the 5-minute staleness check (timestamp +
300_000 < now) was still true on the next block tick. Combined
with the 6-12s block polling that drives updatePrices(), this
made the same handful of unlisted tokens generate ~50 upstream
calls per hour per API instance — the dominant CoinGecko quota
consumer after #110.
Bump the entry's timestamp on a failed fetch too, so the retry
honours the same 5-minute window as a successful fetch.
