Fix operator answers not saving from terminal

Operator answers to radio, dropdown, and text prompts now record correctly no matter how a run is launched, fixing a crash when a later phase read a measurement from an earlier prompt.

• Fixed bound measurements not being saved on terminal (tofupilot run) and automated --json runs, which previously worked only in the kiosk and Studio.
• Fixed text prompts skipping length and pattern validation on automated runs, so invalid values are now rejected consistently across every surface.
• Improved prompts to record their default value when left unanswered, matching the kiosk.
