* wdclient, dailyrun: add equal jitter to retry backoff
Prevents thundering-herd retries when many clients recover from a
transient failure at the same instant (e.g., filer restart, network
partition healing).
Uses equal jitter: wait in [d/2, d) instead of deterministic d.
This bounds the maximum wait while still desynchronizing clients.
Files:
- weed/wdclient/filer_client.go (LookupVolumeIds retry loop)
- weed/s3api/s3lifecycle/dailyrun/dispatch.go (dispatchWithRetry)
Tests added for bounds, zero/negative inputs, and distribution sanity.
Closes#9735

Adds standard Kubernetes liveness/readiness endpoints to all HTTP
servers that were missing them:
- S3: adds /readyz (already had /healthz)
- IAM: adds /healthz and /readyz (had none)
- Volume: adds /readyz (already had /healthz)
- Filer: adds /readyz on default and readonly mux
- Master: adds /healthz and /readyz at root level
(preserves existing /cluster/healthz)
All endpoints reuse existing health handlers or return 200 OK as a
minimal foundation. Future PRs can enhance /readyz with dependency
checks without breaking the contract.
Closes#9736
