Match earnings decoding to PostgreSQL’s aggregate type.

bounties.amount is BIGINT, so PostgreSQL returns NUMERIC for SUM(amount). Both visible queries decode that result with Row::get::<i64>, which can panic when the visibility list is non-empty. Cast the aggregate to BIGINT with explicit overflow handling, or decode it as NUMERIC and convert it safely. The existing unfiltered methods use the same unsafe decoding pattern.

The integration test calls /api/v1/bounties/stats and asserts total_earned == 300, so it exercises the visible leaderboard decode path.

Review comment at @crates/gitlawb-node/src/db/mod.rs at line 4621:
Update the earnings aggregate decoding that feeds the `row.get::<i64>` total in
the bounty stats queries: handle PostgreSQL’s `NUMERIC` result from
`SUM(amount)` safely, either by casting the aggregate to `BIGINT` with overflow
handling or by decoding `NUMERIC` and converting safely. Apply the fix to both
visible and unfiltered query paths while preserving the expected `total_earned`
value.
