Fixed Port Validation (Sentry)

[IllianiBird]

• Fixed port parsing to use MathUtility and return the Default Port in the event a malformed port is entered by user
• Ensured the port value is clamped to valid bounds using the clamp utility method. This prevents invalid ports outside the range of MMConstants.MIN_PORT and MMConstants.MAX_PORT.
• Added missing error string for port validation
