* fix: add timeout to waitForWaConnection to prevent indefinite hangs
If Baileys fails to emit a 'connection.update' event with either 'open'
or 'close' status (e.g. due to network issues or internal errors), the
waitForWaConnection promise hangs forever, blocking the entire monitor
loop.
Add a configurable timeout (default 60s) that rejects the promise and
cleans up the event listener if no connection state is received in time.
The timeout is backward-compatible as an optional parameter with a
sensible default.
* test: add coverage for waitForWaConnection timeout path
- Test that promise rejects with descriptive error after timeout
- Test that event listener is cleaned up after timeout
- Test that timer is cleared when connection opens before timeout
* fix: default timeoutMs to 0 to preserve QR login behavior
The 60s default broke the QR login flow in login-qr.ts, which calls
waitForWaConnection without a timeout and expects to wait up to 3 minutes
while the user scans. Change the default to 0 (wait forever, matching
original behavior) and pass the 60s timeout explicitly at the monitor
callsite where it's actually needed.
