fix(ecstore): harden issue3031 multipart validation path (#3106)

* fix(ecstore): harden issue3031 multipart validation path

- clear stale multipart part destinations before rename fan-out
- add repeated part overwrite regression coverage
- reduce remote disk startup false-fault escalation to suspect-first
- refine remote locker diagnostics and lower scanner leader-lock log noise
- add a dedicated 4-node issue3031 docker validation script

* refactor(admin): inline console version json macro

- drop the unused serde_json::json import in admin console
- call serde_json::json! inline in version_handler
- keep the console version response behavior unchanged

* fix(remote-disk): recover suspect health on probe success

- record probe success during remote disk health checks so suspect drives recover
- use async_with_vars for the remote disk health probe test
- make the missing-listener test assert the state transition more robustly
