superseed-sepolia op-reth: use conduit-op-reth image + historicalrpc

Chain 53302 is legacy Canyon-at-genesis (block 0 has no Shanghai
withdrawalsRoot). Upstream op-reth always injects it and computes the wrong
genesis hash 0xfa6f21ae vs canonical 0x7274a90e, so it crash-loops against
the DB. conduit-op-reth has legacy-Canyon genesis compatibility for 53302.

Regenerated from context.yml (reth client_image override) + op-reth.yml
template (historicalrpc for superseed-sepolia fresh-sync backfill).
