Several tomo_scan()/tomo_alignment_scan()/find_rotation_center() tests started failing (CI) after recent commits on this branch introduced new input()-backed confirmation/sample-name prompts, an alignment_scan_progress GUI proxy, and tomo_queue_execute()'s interactive=False kwarg -- none of which the existing test fixtures or assertions were updated for. Mock/bypass the new prompts and GUI calls, add the missing _alignment_scan_progress_proxy to the bare-object test fixture, and update two assertions (tomo_queue interactive kwarg, account-less sample registration) to match the intended new behavior.
