fix: Fix Claude integration tests by ensuring provider registration

The Claude webhook integration tests were failing because the provider
wasn't being registered before the routes were imported. This was due
to the conditional check that skips provider initialization in test mode.

Changes:
- Move environment variable setup before any imports
- Import Claude provider before importing webhook routes
- Remove duplicate provider registration from beforeAll hook

This ensures the Claude provider is properly registered with the webhook
registry before the tests run.
