Use sharding in CI workflows (#619)

* Bump block numbers

* Use vitest sharding in CI workflow

* Remove non-archive radiumblock endpoint for BridgeHub Kusama

* Merge sharded test reports and shard update-known-good workflow

- ci.yml: add --reporter=blob per shard, upload as artifact, and a
  merge-reports job that combines them via vitest --merge-reports so
  the run summary shows one unified set of test totals instead of one
  section per shard.
- update-known-good.yml: shard the tests matrix 3 ways to match ci.yml,
  and disambiguate the failed-chains artifact name by shard so the
  notify job downloads all per-(network, shard) reports without
  collisions.

* Replace pruned Bulletin endpoint with bulletin-rpc.polkadot.io

The previous amperfix endpoint has pruned state at PET's pinned block
(probed live: UnknownBlock error in 136ms). bulletin-rpc.polkadot.io
serves the same block in 110ms. simplystaking's spectrum endpoint is
also pruned and not used.

* Disambiguate blob report filenames per (network, shard)

Vitest's default blob filename is blob-${shard}-${total}.json, which
collides across networks when 'actions/download-artifact' merges all
artifacts into one directory. Each shard now writes to a uniquely
named file, so the merge-reports job can parse all six blobs without
the JSON-after-JSON SyntaxError seen in run 26061812546.
