test(cli-logging): preserve caplog across repeated init

[PakitoSec]

Summary

• update the CLI log capture fixture to attach pytest's capture handler directly to the cyvest.cli logger before logurich reinitializes logging
• clean up the temporary handler after each test so repeated CLI setup and teardown does not break captured log assertions
• add regression coverage that invokes cli engines twice and verifies the expected log output is still captured

Testing

• regression coverage added in tests/test_cli.py for repeated CLI initialization and log capture behavior
