litellm_fix: resolve all failing mapped tests on CircleCI

Fixes for mapped test failures across multiple test suites:

1. **DataDog Integration** (test_datadog_llm_obs_agent):
   - Fixed DD_API_KEY/DD_SITE requirement check to respect agent mode
   - When LITELLM_DD_AGENT_HOST is set, API key and site are optional

2. **Prometheus Logging** (enterprise callbacks):
   - Updated test assertions to include new model_id label
   - Added client_ip and user_agent labels where expected
   - Fixed label argument ordering to match implementation

3. **Proxy Server Tests** (get_image):
   - Made tests async (get_image is an async function)
   - Fixed os.path.exists mocking to not return True for cache file
   - Removed unnecessary os.getenv mocking

4. **Vector Store Tests**:
   - Fixed prisma_client patch path (use proxy_server.prisma_client)
   - Added missing team_id and user_id attributes to mock UserAPIKeyAuth

5. **Key Management Tests**:
   - Added 5-second buffer for timing comparison in budget_reset test

6. **Vertex AI Passthrough Tests**:
   - Updated test to expect URL preservation when project/location present

7. **Presidio Guardrail Tests**:
   - Removed incorrect assertion about session closure (sessions are cached)

8. **Azure SDK Tests**:
   - Added acancel_batch to skip list (uses cached client)

9. **Cost Calculation Tests**:
   - Fixed expected calculation to account for double-counting detection
