Guided tour rebuilt around Project Templates + real proposals

The guided tour got a substantial rework to match how the app actually flows today.

Catalog leg starts with Project Templates. Project Templates is the top of the catalog hierarchy — the framework the AI pulls from when it builds a proposal. The tour now opens the Shower Remodel template and walks the full hierarchy in one place: template → lines → materials + tasks per line. After that, the individual Services, Materials, and Find Products pages register as per-type detail views of the same data, so we don't deep-dive each one anymore.

No more sample project. Instead of poking at a seeded "Maple St." demo, the tour walks you through building your first real proposal end-to-end:

• Tap + New Project, fill in a name and client.
• Drop one input — a 15-second voice note is the fastest path. Biddy gives you a sample script if you'd rather use placeholder content.
• Tap Draft Scope of Work, review the draft, then Lock & Build.
• Biddy waits while materials, tasks, and pricing generate (about 30–60 seconds), then walks you through the finished proposal.

Cost Analysis now has source-tag chips on every line — FROM TEMPLATE means I sourced from your catalog (trustworthy), FROM AI means I had to fill in a guess (double-check before bidding). Same chip pattern on the Tasks tab.

Tasks tab is live the moment a proposal is built. Tasks used to fire only after sign — now they generate alongside materials and cost analysis, so you can see the full crew checklist before you send the proposal out.
