Missing socket tests post program detach

Scenario:
- load sock addr program - that returns PERMIT/REJECT verdict
- test a socket connection to check if the verdict is honored
- detach the program, or terminate the application that loaded the program
- test a socket connection - should run uninhibited.

Locate the existing sock addr program and socket connection tests, then run them to understand how verdicts are checked. Add coverage for detaching the program or terminating its loader, verifying a subsequent socket connection is no longer restricted. Done means both cleanup paths confirm uninhibited socket behavior.
