This PR refactors EasyTier's configuration flags system across protobuf definitions, TOML/API persistence, runtime reconciliation, and the CLI.
It introduces a synthesized FlagsPatch protobuf message with optionize and pbjson support to track field presence reliably, replaces manual CLI flag boilerplate with dynamic schema-driven clap argument generation, and
establishes Flags::resolve(patch) as the single source of truth for runtime defaults.
