test(cli): add config file precedence integration tests

[kariy]

Summary

• Improve --config arg help message to clarify file vs CLI precedence
• Add 9 integration tests in crates/cli/tests/config_file.rs covering the SequencerNodeArgs::with_config_file() merge logic:
  • File-only values across all option groups (sequencing, execution, dev, gpo)
  • CLI args taking precedence over file values
  • Partial config files with serde defaults for unset fields
  • no_mining bool merge in both directions
  • DbOptions field-level merge (CLI dir override, file migrate preserved)
  • DevOptions field-level merge (CLI seed/accounts, file no_fee/no_account_validation)
  • Empty config file edge case
  • Hex gas price parsing (0xff, 0x10) via custom deserializer

Test plan

• cargo nextest run -p katana-cli --test config_file — all 9 tests pass
• Tests verified stable across multiple consecutive runs
