Allow manual OAuth URL entry without waiting full callback timeout

[cook1e0]

This change improves the user experience of the manual OAuth fallback.

In the existing auth.py, the code waits the full 120 seconds for an automatic callback before prompting the user to paste the callback URL. On remote servers or SSH‑tunneled setups where the automatic callback cannot reach the container, this forces users to wait unnecessarily.
The patch adds queue to the imports and replaces the blocking wait loop with a concurrent input listener. A background thread listens for manual input while still waiting for the automatic callback, checking both sources and proceeding as soon as either one arrives. If neither a callback nor manual input is received within 120 seconds, it raises an error.

This allows users to paste the callback URL immediately without waiting, while still supporting automatic callbacks when they work.
