Fix hybrid reconnect and evidence snapshot races

[masarray]

Summary

• reuse the same ARIEC-authoritative hybrid planning pipeline after MMS reconnect, including fresh RCB availability revalidation
• synchronize planning, activation, report-slice mutation, warning de-duplication, and snapshot capture in the physical-validation tracker
• prepare patch release v1.6.31 because these review findings arrived after v1.6.30 publication

Reset per-point report evidence before rebuilding plans

When a point had ReportChangeVerified set before the connection dropped, this reconnect path resets the hybrid tracker but leaves that flag and ReportTrafficSeen intact in session.States. The first GI or integrity update from the newly started plan is therefore included by ReceiveReportSlicesAsync in verifiedReportPointKeys, causing the fresh validation snapshot to claim a change-verified point even though no change has occurred on the new association. Clear the per-association report evidence flags before starting these rebuilt plans so reconnects cannot produce false physical-validation evidence.
