Build a first-run onboarding checklist for connecting a wallet and funding the vault

[greatest0fallt1me]

Description

This is a UI/UX onboarding issue. The landing page in src/App.tsx lists consumer/developer steps as static copy, but once inside the app there is no guided onboarding that tracks whether a user has connected a wallet, deposited USDC, or browsed an API. New users have no sense of progress or next step.

Requirements and Context

• Add a dismissible onboarding checklist surface (e.g. on /dashboard) reflecting the four consumer steps from App.tsx.
• Each item should show completed/incomplete state and link to the relevant route (Billing deposit, Marketplace).
• Persist dismissal/progress in localStorage (consistent with callora-theme usage) and be fully keyboard accessible.
• Must be secure, tested, and documented
• Should be efficient and easy to review

Suggested Execution

1. Fork the repo and create a branch

   git checkout -b feature/onboarding-checklist

2. Implement changes
   • src/components/OnboardingChecklist.tsx (new) rendered on the dashboard
   • src/App.tsx — mount the checklist and wire step links
   • src/index.css — token-driven checklist styles
3. Test and commit
   • npm run dev, verify progress states, dismissal persistence, and keyboard use
   • Include test output and notes in the PR

Example commit message

• Fully keyboard accessible and themed in both modes

Guidelines

• Keep persistence keys consistent with existing callora-* naming
• Clear documentation and inline comments
• Timeframe: 96 hours
