fix(fast-inbox): bump the proving broker database schema version (A-1375)

Persisted broker jobs are keyed by the numeric ProvingRequestType, and this branch
inserts BLOCK_ROOT_MSGS_ONLY_ROLLUP into the middle of the enum, shifting every later
value. A prover restarted in place over an existing data directory would otherwise
dequeue a stale job and hand it to the wrong prover method; the version check already
discards a database whose schema version does not match.
