feat: TR-069 CWMP state machine hardening + exchange viewer improvements

- TR-069 CWMP state machine hardening (14 phases): shared event utility,
  multi-event routing, GPN circuit breaker, IdleState GPN guard, expanded
  GPN fault codes, CriticalReadsState, ConfigEval GPN guard, task queue
  race condition fix, explicit error handling, terminal states
  (OperationalState/PartialOperationalState), consolidated reclassify,
  crash pattern detection, removed enqueueImmediate, state flow wiring
- Fix SOAP Fault not processed by state machine (soap-env:Fault detection)
- Fix GPN circuit breaker not persisting after session drops
- Fix CriticalReadsState GPV response parsing (xsi:type normalization)
- Fix CriticalReadsState not processing GPV response values
- Skip SPV when device is already compliant (ProvisioningCode check)
- Add Device.DeviceInfo.ModelName to critical reads GPV
- Fix TypeError on DeviceDetail parameters view (null guards)
- Log empty 204 responses in exchange trace UI
- TR-181 catalog: type corrections and new entries (+6640 lines)
- SequenceViewer: replace session-nav buttons with compact dropdown select
- SequenceViewer: fix CPE/ACS lifeline headers wrapping to 2 lines
- Add 20 unit tests for state machine fixes (SOAP Fault, GPN circuit
  breaker, CriticalReads, stale session, ConfigEval/ComplianceUpdate skips)
