Fix event-loop starvation, MeshCore stability, config-page hardening

- mesh_data_store.py / env/store.py: make refresh() async, offload blocking
  polls via asyncio.to_thread/gather so 7 lockstep sources no longer starve
  the shared event loop.
- main.py: gather pollers concurrently + set_default_executor thread pool.
- Dockerfile / docker-compose.yml: healthcheck now curls the dashboard for a
  real liveness signal instead of a process-exists check.
- transport/meshcore_transport.py: MeshCore keepalive loop (get_time() every
  120s), reconnect re-arm (_post_reconnect_setup_async from
  _on_connect_event), and MC channel-name normalization
  (_resolve_mc_channel_idx strips a leading #).
- dashboard-frontend: MeshCoreConnection.tsx config-page hardening, new
  ErrorBoundary component, wired into App.tsx.
- tests: fix ~40 call sites broken by refresh() becoming async (
  test_generic_http.py, test_store_received_delta.py,
  test_store_wzdx_persist.py) by wrapping with asyncio.run(), matching this
  suite's existing convention for calling async code from sync test
  functions. Verified: all 40 tests pass.
