fix(ble_log_console): exclude from idf-ci pytest collection to fix CI

idf-ci discovers pyproject.toml pytest config and runs a separate
collection pass with --target all, which finds 0 target tests and
raises RuntimeError. Add to .idf_ci.toml exclude_dirs instead of
deleting tests. Restore all 227 unit tests with lint/mypy fixes.
