cronos-mainnet: add persistent peers and consensus timeouts to prevent sync stall

- Add PERSISTENT_PEERS env var with official cronos seeds
- Add MAX_NUM_OUTBOUND_PEERS=40 and MAX_NUM_INBOUND_PEERS=80
- Add SKIP_TIMEOUT_COMMIT=true for RPC nodes
- Apply these settings to config.toml in init.sh

Fixes block-sync-exit + slow consensus-mode catchup recurrence on rpc-us-50.
