fix(scanner): retain usage across transient peer failures (#6859)

Browse Source 
* test(scanner): cover bucket drive guard lifecycle

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(scanner): recover usage floor from fenced backups

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(scanner): retry transient activity probes

Retry one failed scanner activity probe after a bounded reconnect when the failure is transport-like or timed out. Keep protocol and response validation failures fail-closed.

* fix(scanner): retain post-scan observations

Preserve a complete scanner walk as a non-converged observation when the final activity probe is unavailable. Advance the cycle as partial without acknowledging dirty usage.\n\nCo-Authored-By: heihutu <heihutu@gmail.com>

* fix(scanner): classify publication lease deferrals

Distinguish persistence budget and lease deadline deferrals from unavailable activity baselines, and ensure lease-gate deferrals update usage metrics. Keep the fixed lease gate fail-closed while storage-owned commit scope work remains pending.

* fix(scanner): preserve publication lease defer reasons

Keep lease expiry and release failures distinct from activity baseline failures so scanner freshness metrics and cycle outcomes identify the publication barrier that blocked progress. Preserve fail-closed behavior.

* fix(scanner): reuse recovered usage baseline for publication

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(scanner): fence legacy usage floor fallback

* fix(scanner): use typed activity timeout error
