Propogate on chain consensus params to tendermint params

Describe your changes and provide context

Fix propagation of on-chain consensus parameter updates into Tendermint consensus state.

Governance proposals can update baseapp consensus params such as TimeoutParams, but the app was building ResponseFinalizeBlock.ConsensusParamUpdates from the legacy EndBlock response, which only carries Block, Evidence,
Validator, and Version. As a result, params like Timeout, Synchrony, and ABCI could be updated in app state but never applied by Tendermint.

This change reads the full consensus params from the state selected for commit and sends the complete set in ResponseFinalizeBlock.ConsensusParamUpdates.

• Propagate full consensus params in FinalizeBlocker.
• Add BaseApp.GetConsensusParamsForStateToCommit().
• Deep-copy all consensus param sections before returning finalize response:
  • Block
  • Evidence
  • Validator
  • Version
  • Synchrony
  • Timeout
  • ABCI
• Add regression coverage for full consensus-param propagation.

PR Summary

Medium Risk
Changes core FinalizeBlock/consensus-parameter wiring; incorrect propagation could affect validator timeouts and ABCI behavior network-wide, though scope is focused and tested.

Overview
FinalizeBlock now sends Tendermint the full on-chain consensus parameter set from the state being committed, instead of rebuilding ConsensusParamUpdates from EndBlock (which only carried Block, Evidence, Validator, and Version). Governance-driven updates to Timeout, Synchrony, and ABCI can therefore actually reach the consensus engine.

Both optimistic and non-optimistic finalize paths call new GetConsensusParamsForStateToCommit() on BaseApp and pass the result into getFinalizeBlockResponse, which deep-copies all param sections via cloneConsensusParams before returning the ABCI response. Regression coverage is added in app/consensus_params_test.go.

The FlatKV EVM Migrate integration-test matrix job is removed from .github/workflows/integration-test.yml (memiavl→FlatKV migration CI row only; other FlatKV jobs remain).
