Release v3.14.0-beta.7

Added

• Arris SB8200 modem-basic variant (URL Token, v6 hardware). v6 hardware
  does not issue a session cookie on login; this variant uses the URL token
  strategy without cookie credential reuse. Status: awaiting_verification.
  Related to #170.
• ModemSnapshot.to_event_payload() and HA event bus integration. Core
  now produces a structured EventBusPayload (model, ISP, status, channel
  counts, collection timestamp) on every successful poll. The HA coordinator
  fires this as the cable_modem_monitor_data_updated event, enabling
  downstream integrations to consume live modem data without coordinator
  coupling. Related to #169.

Changed

• Orchestration logging migrated to typed OrchestratorEvent dataclasses.
  All log output from the orchestration layer now flows through a single
  log_event() adapter. No runtime behavior change.
• HA adapter: dev tools extracted to dev_tools.py. async_request_modem_refresh,
  service registration, and related utilities moved from services.py into a
  dedicated module. No behavior change.
