### Description
This PR replaces lockRow + Java increment + update pattern in
getNextTopologyUpdateSequenceNumber and
getNextRoutingPolicyUpdateSequenceNumber with atomic SQL using
LAST_INSERT_ID:
UPDATE ... SET seq_no = LAST_INSERT_ID(seq_no + 1) WHERE id = ?
SELECT LAST_INSERT_ID()
InnoDB serializes concurrent UPDATEs on the same row, and
LAST_INSERT_ID(expr) stores the result in connection-local state, so each
caller gets a unique monotonically increasing value without explicit row locks.
Also captures the return value of persist() in the find-or-create
initialization path — the original code discarded it, relying on reflection to
populate the ID field on the original object.
Removes the empty try/finally blocks from both methods.
