Wrap `open_autorecon_ws()` body for comms failures

Add outer `try/except` around the nursery block in
`open_autorecon_ws()` to catch any `NoBsWs.recon_errors` that
escape the inner reconnect loop, logging a warning instead of
propagating.

Also,
- correct `NoBsWs.recon_errors` typing to `tuple[Type[Exception]]`.
