fix(ecstore): harden issue3031 multipart validation path

[houseme]

Related Issues

Fixes #3031.

Summary of Changes

• Clear stale multipart part and part.meta destinations before the per-disk rename fan-out so repeated uploads of the same part number follow the MinIO overwrite behavior.
• Add regression coverage for repeated multipart part overwrites and keep complete/list operations bound to the latest uploaded part state.
• De-sensitize remote-disk startup health handling so the first network-like failure transitions to Suspect before escalating to Offline, reducing false startup fault noise.
• Refine remote locker diagnostics, identify scanner leader-lock traffic as unrelated local warning noise, and remove that noise from the default warning surface while preserving connection eviction behavior.
• Add a dedicated 4-node Docker validation script for issue 3031 with S3 readiness gating, warp execution, and summary/log collection.
• Inline serde_json::json! in the admin console version handler and drop the now-unused import without changing behavior.

Verification

• cargo test -p rustfs-ecstore repeated_upload_part_overwrites_previous_part_state -- --nocapture
• cargo test -p rustfs-ecstore multipart -- --nocapture
• cargo test -p rustfs-ecstore remote_disk -- --nocapture
• cargo test -p rustfs-ecstore remote_locker -- --nocapture
• cargo check -p rustfs-ecstore
• bash scripts/validate_issue_3031_docker.sh --skip-build
• bash scripts/validate_issue_3031_docker.sh --force-build
• make pre-commit

Impact

• Local 4-node Docker validation no longer reproduces issue warp multipart-put can fail with Storage resources are insufficient for the write operation #3031 under the validated warp multipart-put profile.
• Multipart overwrite handling now more closely matches MinIO semantics for repeated part uploads.
• Remote-disk and scanner leader-lock warning noise is reduced in the default local validation surface.
• No intended API or user-facing behavior changes beyond multipart-path hardening and quieter diagnostics.

Additional Notes

• Final local validation artifact: target/issue3031/20260528-205330/summary.txt.
• This validation proves the current local 4-node Docker scenario no longer reproduces the issue; it does not prove that every external 4-node environment is fixed.

Pull request overview

This PR hardens RustFS’s multipart upload handling (issue #3031) to better match MinIO overwrite semantics under repeated part uploads, while also refining distributed diagnostics/health handling and adding a local 4-node Docker validation workflow.

Changes:

• Clear stale multipart part payload/metadata before per-disk rename fan-out and add a regression test for repeated part overwrites.
• De-sensitize remote-disk health transitions (Suspect before Offline) and reduce warning noise for scanner leader-lock remote locker traffic.
• Add a dedicated 4-node Docker validation script and small admin console cleanup (inline serde_json::json!).
