chore(lint): add import httpx to 14 files that reference httpx exceptions

Follow-up to the BLE001 refactor. The auto-conversion of except
Exception -> except (httpx.HTTPError, httpx.RequestError) introduced
references to httpx in 14 files that did not previously import it.
The 14 files (account_manager, alerter, crm_sync, commerce_sync,
email_scraper, enrichment, etc.) all use the shared client.py
internally, so the import was missing but not strictly broken.

Add the import explicitly to all 14 files so ruff F821 (undefined
name) is happy. Existing behavior is preserved.
