chore: remove replay authority override

[thlorenz]

Summary

Remove the unused ledger replay validator-authority override feature.

Details

Configuration

Removes ledger.replay-authority-override from LedgerConfig and the example config. This also removes the corresponding environment variable support for MBV_LEDGER__REPLAY_AUTHORITY_OVERRIDE through normal config deserialization.

The replica-mode authority override remains supported via validator.replication-mode.replica.authority-override.

Ledger restore tests

Removes integration test helpers and duplicate restore test variants that existed only to exercise the replay override path. The remaining ledger restore tests now use the standard validator setup paths.

Release Notes

• Chores
  • Removed the optional validator authority override setting used during ledger replay.
  • Updated ledger restore and replay tests/utilities to stop accepting or using authority override inputs, and to consistently use standard validator initialization.
  • Adjusted related helper signatures and test assertions to match the simplified restore/replay workflow.

📝 Walkthrough

Walkthrough

This PR removes the replay_authority_override feature entirely. The replay_authority_override: Option<SerdePubkey> field is deleted from the LedgerConfig struct along with its Default initialization, the SerdePubkey import is dropped, and the corresponding MBV_LEDGER__REPLAY_AUTHORITY_OVERRIDE documentation is removed from config.example.toml. Two exported test helper functions (setup_offline_validator_with_authority_override and setup_validator_with_local_remote_and_authority_override) are removed from the integration test library. All four ledger-restore integration test files are updated to drop the authority_override parameter from their local read/read_ledger helpers, remove the conditional branching that selected the override setup path, and remove now-unused imports.
