Ping QiuandClaude Opus 4.6 c39080ceaa feat: Phase 4A CP4b-4 -- HA integration tests, admin HTTP, 5 bug fixes ...

Add HTTP admin server to iscsi-target binary (POST /assign, GET /status,
POST /replica, POST /rebuild) and 7 HA integration tests validating
failover, split-brain prevention, epoch fencing, and demote-under-IO.

New files:
- admin.go: HTTP admin endpoint with input validation
- ha_target.go: HATarget helper wrapping Target + admin HTTP calls
- ha_test.go: 7 HA tests (all PASS on WSL2, 67.7s total)

Bug fixes:
- BUG-CP4B4-1: CmdSN init (expCmdSN=0 not 1, first SCSI cmd was dropped)
- BUG-CP4B4-2: RoleNone->RoleReplica missing SetEpoch (WAL rejected)
- BUG-CP4B4-3: replica applyEntry didn't update vol.nextLSN (status=0)
- BUG-CP4B4-4: PID discovery killed primary instead of replica (shared
  binPath; fixed by grepping volFile)
- BUG-CP4B4-5: artifact collector overwrote primary log with replica log
  (added CollectLabeled method)

Also: 3s write deadline on WAL shipper data connection to avoid 120s TCP
retransmission timeout when replica is dead.
