Closes #158
Closes #159
Closes #160
Closes #161

Summary

Adds the four requested contract fixes: admin-controlled reputation escrow rotation; zero-weight ratings no longer consume a rater/ratee aggregate slot; admin-managed dispute panel and threshold updates; and a configurable escrow dispute timeout (seven days by default). Panel changes invalidate existing approvals, and timeout changes apply only to future disputes. Contract references, deployment initialization, and timeout messaging are synchronized.
