test: add streaming tail worker test for logWarning() visibility

Add a two-worker test that exercises several logWarning() code paths and
verifies the warnings are visible to a streaming tail worker:

  - FormData body with a custom Content-Type header (Body::Body)
  - Null-body status with zero-length body (Response constructor)

The "trigger" worker generates warnings in its fetch() handler, invoked
via a service binding from its test() entrypoint. The "tail" worker
collects streaming tail events and asserts that all expected warning
substrings appear within a polling timeout.
