P1 Badge Avoid leaving a yarl URL in the event dictionary

When url_raw is true, this assignment mutates the same sub_step dictionary that HttpEngine.run later passes to BaseEngine.process_conditions. That path serializes the event with json.dumps—and successful events are also serialized in submit_logs_to_db—but yarl.URL is not JSON-serializable, so raw requests end with a TypeError and cannot record a finding even when the Apache response matches. Convert the URL only in a copied request dictionary, or restore the string before processing, and cover the flag through HttpEngine.run.

url_raw is popped from request_options before the URL(..., encoded=True) conversion runs. If the conversion raises (e.g., due to invalid percent-escapes or other characters that are only accepted in the non-encoded constructor), the caller’s retry loop will run again with url_raw already removed and will silently fall back to the default URL normalization path, defeating the opt-in behavior. Consider reading the flag with get() and only pop()-ing it after a successful conversion (or build a shallow copy of request_options for the aiohttp call and leave the original dict untouched).
