* Refactored the BACnet/SC datalink initialization order by moving certificate file checks and hub connection registration to occur after datalink initialization
* Replaced stdlib rand() with platform-specific cryptographically secure random functions (RtlGenRandom for Windows, getrandom for Linux, arc4random_buf for BSD) to generate UUID and VMAC addresses, preventing duplicates that broke connections
* Enabled conditional debug output in BACnet/SC components when BUILD=debug is specified
* Fixed WriteProperty error code for PROP_FD_BBMD_ADDRESS and PROP_FD_SUBSCRIPTION_LIFETIME properties.
* Fixed dead-code warning after enabling all datalinks for basic network port object using the property list as the R/W checking for the port type.
