test(krisp): scope importlib.metadata.version mock to imports only

The four krisp test files installed a process-wide mock of
importlib.metadata.version with `patch(...).start()` at module level and
never called .stop(). Once any of these files was collected, the mock
leaked across the rest of the test session, returning '0.0.0-dev' for
every version check. This corrupted unrelated tests that triggered
transformers' import-time dependency check (e.g. lazy imports of
LocalSmartTurnAnalyzerV3) — transformers saw tqdm=='0.0.0-dev' and
refused to load.

Wrap the pipecat imports in `with patch(...)` so the mock is active
during import (where pipecat's krisp version check needs it) and torn
down before any tests run.
