fix: order chain queries by rowid so Pezkuwi's chains register first

SELECT * FROM chains had no ORDER BY - SQLite gives no ordering guarantee
for that, so registration/connection order across ~98 chains was
effectively unpredictable per run. The merged chains.json lists Pezkuwi's
own chains first (wallet-utils' merge_chains()), and CollectionDiffer's
findDiff()/Room's batch insert both preserve that order on first sync, so
ordering by rowid (insertion order) makes Pezkuwi's own chains reliably
register and start connecting first/early, instead of being interleaved
unpredictably among ~90+ Nova-inherited chains where they could end up
processed dead last - observed directly: a fresh install took 45+ seconds
without a single Pezkuwi-related registration/connection attempt.

No user should wait minutes for their own wallet's native chain to even
start syncing after install, regardless of whether the eventual outcome
is correct.
