Subject: [PATCH] Optimize get_prediction_aip_http_port

The optimization replaces the explicit `None` check and length validation with a single truthiness test. The original code uses `serving_container_ports is not None and len(serving_container_ports) > 0`, which requires two separate evaluations: a None check and a length calculation. The optimized version uses `if serving_container_ports:`, which leverages Python's truthiness rules where empty sequences (lists, tuples) and `None` both evaluate to `False`.

This change eliminates the `len()` function call, which has overhead even for small sequences, and reduces the boolean expression from two operations to one. The line profiler shows the conditional check time dropped from 64,650ns to 40,013ns (38% reduction), contributing significantly to the overall 33% speedup.

The optimization is particularly effective for:
- **Empty containers** (lists, tuples): 47-58% faster as shown in tests, since no length calculation is needed
- **Large sequences**: 51-68% faster improvements, as `len()` overhead becomes more significant with larger containers
- **None inputs**: 11-21% faster, eliminating the explicit None comparison

The truthiness approach is idiomatic Python and maintains identical behavior - both `None` and empty sequences return the default port, while non-empty sequences return their first element.
