fix dshackle chain labels: hoodi, rootstock-testnet, ronin-saigon + registry refresh drift

- ethereum-hoodi composes: chain ethereum -> hoodi (was mislabeled as mainnet)
- rootstock-bamboo: chain rootstock -> rootstock-testnet
- ronin-saigon op-reth: empty chain -> ronin-saigon (fresh DRPC registry now
  carries saigon at chainid 202601; stale local upstreams.yml had dropped it)
- assorted regen drift from fresh chain registry
