fix(traffic): keep lifecycle statements under SQLite's variable limit

Three statement shapes bound one SQL variable per row and failed past
SQLite's limit, which a node can reach by itself with the clients and
inbounds it reports: the depleted-client lookup and disable in
disableInvalidClients (stopping every expiry and quota check), the
whole-slice Saves of renewed inbounds and traffics (stopping renewals),
and Preload("ClientStats") over all inbounds (stopping config builds).
The IN lists are chunked, the Saves go 100 rows at a time, and client
stats are attached in chunks instead of preloaded.
