Fix type errors in runner and add to pyright checked set

Make required parameters non-optional: LiveKitRunnerArguments.token,
_create_telephony_transport args. Use os.environ[] instead of
os.getenv() for required WhatsApp env vars. Guard spec/loader None
in module loading. Tighten sip_caller_phone guard in daily.py.
