docs: design spec + plan for grid-wallet-prod (phase 1: fork, remove config sidebar)

[pengying]

Summary

Design spec and implementation plan for forking components/grid-wallet-demo into components/grid-wallet-prod, the starting point for a live production demo (real Grid API requests in Phase 2).

Phase 1 scope (implemented in the stacked PR above): fork the app to port 4001, remove the ConfigurePanel sidebar so the layout is phone + API panel, hardcode passkey sign-in with the Fintech use case. Live production API integration is explicitly deferred to a Phase 2 spec.

Greptile Summary

This PR adds the Phase 1 design for the grid-wallet-prod fork. The main changes are:

• Fork the existing wallet demo onto port 4001.
• Remove the configuration sidebar and related mobile navigation.
• Fix sign-in to passkey and the use case to Fintech.
• Defer live API requests and production key handling to Phase 2.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed documentation.
• The planned component and layout changes match the existing demo structure.
• Security-sensitive production integration remains outside this phase.
