refactor(lock): unify NamespaceLock client model and LockRequest API

- Refactor NamespaceLock to use a unified client vector and quorum mechanism,
  removing legacy local/distributed lock split and related code.
- Update LockRequest to split timeout into acquire_timeout and ttl, and add
  builder methods for both.
- Adjust all batch lock APIs to accept ttl and use new LockRequest fields.
- Update all affected tests and documentation for the new API.
