Sync genesis.json from morph-l2/run-morph-node mainnet/node-data/config/,
keeping only node0–node2 to match the live 3-validator network (config.toml
already lists 3 persistent_peers). Removes stale node3–node6 entries.
morphnode --mainnet does NOT self-generate config (crash: Config File not found in
/db/config). Add init container that seeds the committed morph/mainnet/node-data/config/
(config.toml + genesis.json, from run-morph-node) into /db/config (no-clobber). Node
renamed morph-node -> morph (cleaner; vol _morph, MORPH_MAINNET_MORPH_* env).
