Elizabeth Thompson f8cf65404a fix(screenshots): catch empty-bytes tiled result and set ERROR on falsy image ...

Two bugs that could cause blank PDFs to re-trigger indefinitely:

1. webdriver.py: tiled fallback used `if img is None:` which let b""
   (returned by combine_screenshot_tiles on an empty tile list) pass
   through silently. Changed to `if not img:` to catch both cases.

2. screenshots.py: compute_and_cache had no else branch after
   `if image: cache_payload.update(image)`. When get_screenshot returned
   None or b"" without raising, status stayed at COMPUTING instead of
   ERROR, causing is_computing_stale() to re-trigger the task
   indefinitely after THUMBNAIL_ERROR_CACHE_TTL. Added
   `else: cache_payload.error()` so failed screenshots always transition
   to ERROR and use the controlled TTL back-off.
