Fix test imports, Nox discovery, and unblock tests

This commit addresses several issues I found after the initial creation
of the test suite for `examples/advanced_operations/`:

1.  **Corrected Test Imports:**
    *   I removed `sys.path.insert()` calls from all newly added test files
        in `examples/advanced_operations/tests/`. This resolves
        `ModuleNotFoundError: No module named 'examples'` when tests are
        run by a central runner like Nox or pytest from the project root.

2.  **Updated Nox Test Discovery:**
    *   I modified `noxfile.py`:
        *   I reverted the primary `TEST_COMMAND` to use `-s=tests` for
            discovering tests in the original `tests/` directory. This should
            resolve import issues for existing tests (e.g., `pyfakefs`, `fixtures`).
        *   I added a new `EXAMPLES_TEST_COMMAND` specifically for tests in
            `examples/advanced_operations/tests/`.
        *   Both Nox sessions (`tests` and `tests_minimum_dependency_versions`)
            now execute both test commands, ensuring all tests are run and
            included in coverage.

3.  **Unblocked `test_get_ad_group_bid_modifiers.py`:**
    *   I successfully implemented a custom mock class
        (`MockProtoPlusAdGroupBidModifier`) with a static `pb` method.
        This resolves the `AttributeError` related to
        `type(modifier).pb(modifier).WhichOneof("criterion")` and allows
        the test to pass.

4.  **Progress on `test_add_smart_campaign.py`:**
    *   I corrected a `TypeError` by ensuring the script's `main()`
        function is called with the correct number of arguments.
    *   The test still faces a known challenge with mocking for the
        `protobuf_helpers.field_mask` utility, similar to issues
        I noted in other tests with complex protobuf message structures.

5.  **General Test Refinements:**
    *   Includes various minor corrections to assertions and mock setups
        in several other test files as I identified during test execution and refinement.

These changes improve the robustness of the new test suite and its
integration with the project's existing testing infrastructure.
