Prototype-based update

This wireframe uses the current quote list pattern from the screenshot, but changes the row meaning. Each row is a full quote container rather than a single door-driven quote record.

What changes

• The first screen is now just the quote list and the new-quote entry point.
• Add New Quote should open the quote overview/workspace so capture starts at the parent quote level.
• The single-order rule is visible in the list state, not hidden in backend logic only.

Why this matters

This removes unnecessary decision clutter from the very first screen and makes the primary task obvious: open an existing quote or create a new quote and start capturing information.
