Fix screenshot directory deletion and update SSL dependencies

Save screenshot_dir to database when scans complete so the directory
is properly cleaned up on scan deletion. Previously the field was never
populated, causing screenshots to remain after deleting scans.

Update sslyze to 6.2.0 and cryptography to 46.0.0 to fix certificate
handling issues with negative serial numbers (RFC 5280 compliance).
