op-reth: emit --disable-discovery (not --nodiscover) for node_sync nodes

op-reth rejects geth's --nodiscover flag, which the op-geth base template
emits for node_sync nodes. Use reth's --disable-discovery instead.

- hashkeychain-testnet: now node_sync/consensus-layer (was execution-layer
  with an empty DB, which could not backfill) + --disable-discovery
- xlayer mainnet/testnet (archive+pruned): --nodiscover -> --disable-discovery
  (these were latently broken on restart)

Fix lives in the op-reth.yml base template so all reth nodes are covered;
the redundant override in op-reth.boba.yml was removed.
