PR Summary

Low Risk
Low risk: this is a dependency-wiring change only, adding an optional field that is currently passed as None and doesn’t alter consensus logic yet.

Overview
Adds an optional strk_exchange_rate_oracle dependency (typed as ExchangeRateOracleClientTrait) to SequencerConsensusContextDeps to support future SNIP-35 dynamic gas pricing.

Wires the new field through consensus manager and orchestrator test utilities, defaulting it to None so existing behavior remains unchanged.
