pingqiuandClaude Opus 4.6 46ef79ce35 fix: stable ServerID in assignments, fail-closed on missing identity, wire into ProcessAssignments

Finding 1: Identity no longer address-derived
- ReplicaAddr.ServerID field added (stable server identity from registry)
- BlockVolumeAssignment.ReplicaServerID field added (scalar RF=2 path)
- ControlBridge uses ServerID, NOT address, for ReplicaID
- Missing ServerID → replica skipped (fail closed), logged

Finding 2: Wired into real ProcessAssignments
- BlockService.v2Bridge field initialized in StartBlockService
- ProcessAssignments converts each assignment via v2Bridge.ConvertAssignment
  BEFORE existing V1 processing (parallel, not replacing yet)
- Logged at glog V(1)

Finding 3: Fail-closed on missing identity
- Empty ServerID in ReplicaAddrs → replica skipped with log
- Empty ReplicaServerID in scalar path → no replica created
- Test: MissingServerID_FailsClosed verifies both paths

7 tests: StableServerID, AddressChange_IdentityPreserved,
MultiReplica_StableServerIDs, MissingServerID_FailsClosed,
EpochFencing_IntegratedPath, RebuildAssignment, ReplicaAssignment
