PR Summary

Medium Risk
Enables SNIP-35 fee proposal logic to call an external STRK/USD oracle by default, which can affect gas pricing behavior and adds runtime dependency on correct oracle configuration.

Overview
Wires the STRK/USD exchange-rate oracle into apollo_consensus_manager by instantiating an ExchangeRateOracleClient and passing it into SequencerConsensusContextDeps (instead of None), enabling SNIP-35 dynamic fee_proposal computation.

Adds apollo_l1_gas_price and apollo_l1_gas_price_config dependencies, and documents that deployments must override the default ExchangeRateOracleConfig.url_header_list (default points to a placeholder) to avoid the oracle failing and fee_proposal freezing at fee_actual.

Always-failing oracle floods shared ETH_TO_STRK error metrics

Medium Severity

The new ExchangeRateOracleClient with the placeholder api.example.com URL will continuously fail, and each failure increments the global ETH_TO_STRK_ERROR_COUNT metric inside spawn_query. With lag_interval_seconds: 1 generating unique quantized timestamps, a new failing query is spawned on every block proposal (~every 3 seconds), producing ~1200 error increments per hour. The existing get_eth_to_strk_error_count_alert in alert_definitions.rs fires at a threshold of 10 per hour, so this will trigger constant false alerts and obscure genuine ETH/STRK oracle failures.
