feat: restore strong typing on TR-069/CWMP protocol layer
- Copy cwmp-1-0..4.ts source classes from cwmp-connector (papaye) into
app/protocol/ as local files (ts-nocheck, external dependency)
- Add soap_envelope.ts: SoapEnvelope, SoapEnvelopeHeader, CwmpID, NAMESPACES
- Add tr069_types.ts: re-exports all CWMP classes + CwmpMessage discriminated
union + typed task payload interfaces (CWMPTaskType, CWMPTaskPayload, etc.)
- Rewrite cwmp_message_builder.ts to use class-based builders instead of raw
XML template strings; add transferCompleteResponse() and soapFault()
- soap.ts: extractCwmpMessage returns CwmpMessage union, adds runtime allowlist
guard against unknown CWMP method names from CPE
- cwmp_middleware.ts: envelope typed SoapEnvelope|null, message CwmpMessage|null
- cwmp_controller.ts: handleInform(informData: Inform), remove any, migrate
TransferComplete and fault to new builder path, drop buildSoapEnvelope import
- task_queue.ts: CWMPTask.type → CWMPTaskType literal union, payload →
CWMPTaskPayload, result → CWMPTaskResultData
- device_action_executor.ts: GPV/GPN/GPA responses typed, no more any
- main_state_machine.ts: DeviceContext.message.data → CWMPTaskResultData,
organizeParameters receives ParameterInfoStruct[] directly
- device.ts: tmpParamValues typed ParameterValueStruct[], organizeParameters
signature updated, updateFromValues typed
- device_id.ts: fromInform typed with DeviceIdStruct
- soap_envelope.ts: remove unconditional <cwmp:noMoreRequests> header
(CPE→ACS only per TR-069 §3.7.1.4)
