Pull request overview

This PR reduces unnecessary network/processing load by (1) ignoring duplicate intercepted-data messages earlier in the interceptor pipeline and (2) making marshalled transaction payload generation deterministic, while also simplifying epoch-start “request block info” delay configuration by moving it to the global EpochStartConfig.

Changes:

• Treat duplicated intercepted data (and already-known equivalent proofs) as ignorable messages (ErrMessageShouldBeIgnored) to avoid redundant processing/propagation.
• Ensure createMarshalledDataV3() output determinism by iterating mini-block maps in sorted key order.
• Refactor epoch-start trigger extra-delay configuration: remove per-epoch field + CommonConfigsHandler accessor and use EpochStartConfig.ExtraDelayForRequestBlockInfoInMilliseconds instead.
