version 5.1.8

- fix: matrix/sms_voipms notifications blocked the event loop on timeout;
  make send_notification async, dispatch all channel drivers as non-blocking
  tasks (asyncio.to_thread for sync drivers, asyncio.wait_for for async);
  update all call sites to fire-and-forget via create_task
- feat: add /about page with version, runtime, uptime counter, and repo link
- fix: hbc_mini plugin data format now matches full hbc client so Host
  Overview displays memory, disk, and network metrics correctly
