feat(cli): D-Bus client wrapper + full subcommand dispatcher

Lands plan tasks C2 (Daemon proxy wrapping all 9 D-Bus methods via
Proxy::new_owned), C3 (status/list/policy-show), C4 (enroll/remove/policy-
set/apply/validate), and C5 (pending/recovery). Bundled because dispatch
needs the bus wrapper to compile cleanly under -D warnings.

Phase 4/5/12 placeholders in the dispatcher: policy apply re-saves to trigger
PolicyChanged; policy validate is a TOML round-trip; pending list and
recovery list are no-op messages until the corresponding D-Bus methods land.

5 clap-parser tests pass (was 5; same — parser shape unchanged in this
commit). Workspace clippy clean.
