client: thread verify=self.verify through screenshot + extraction requests

_scrape_request() already included `verify: self.verify` in its return
dict, but _screenshot_request() and _extraction_request() did not.
On a self-signed-cert API host (e.g. a dev stack with verify=False),
scrape() worked fine while screenshot() and extract() raised
SSLCertVerificationError after 5 backoff retries.

Discovered by the sdk/integration harness: screenshot.basic passed
via the Go SDK but failed via Python with the exact same client
configuration (key + host + verify=False), which narrowed the bug
to the Python request builder.
