<fixed>(ui): fix SIGSEGV when closing.

1. Fixed the segfault problem when closing the program (problem with root certificate).
2. Added some code that is executed before the exit function is called, including releasing all the root certificates that have been loaded.
3. Optimized the preloading code of the root certificate.
