feat(admin): add manual transition job controls

[houseme]

Summary

• Add backend-backed rc admin ilm transition run --async job submission while preserving the existing synchronous run behavior.
• Add rc admin ilm transition status, cancel, and wait commands that use only the RustFS admin job endpoints.
• Extend the core/S3 admin client and typed job response model, including queue/report fields and deterministic CLI JSON/human output.

Testing

• cargo fmt --all
• cargo fmt --all --check
• cargo clippy --workspace -- -D warnings
• cargo test -p rustfs-cli --test admin_ilm
• cargo test -p rustfs-cli commands::admin::tests::test_parse_admin_ilm_transition
• cargo test --workspace
• git diff --check

Notes

• Job state remains backend-authoritative; the CLI does not keep local fake transition state.
• Status, cancel, wait, and async run paths preserve existing admin error mapping for not found, unauthorized, conflict, and unsupported responses.

Closes #1480
