Subject: [PATCH 1/2] RDKEMW-25493: Harden port name validation in audio
 persistence handlers

Add validation for portName before using as persistence key to prevent
injection attacks from whitespace and control characters.
Add security regression test to validate port name checking logic.

Subject: [PATCH 2/2] RDKEMW-25493: Address Coverity false positive on char
 array NULL check

Remove unnecessary NULL checks on char array (portName) to address
Coverity warning. The array is always non-NULL, so only strlen check is needed.
