Minor bugs: incorrect footer year, orphaned DemoContext, unused button component, missing public assets

[Mosas2000]

Summary

Several minor but distinct bugs exist across the frontend that should be addressed for correctness and consistency.

Issues

1. Incorrect Copyright Year in Footer

• File: frontend/src/App.jsx (line 164)
• Current: (c) 2026 TipStream
• Expected: (c) 2025 TipStream or dynamically generated via new Date().getFullYear()
• The year 2026 is incorrect and should reflect the actual launch year or be dynamically set

2. Orphaned DemoContext with No Consumer

• File: frontend/src/context/DemoContext.jsx
• The DemoBanner.jsx component that consumed this context was deleted during the refactoring phase
• DemoContext.jsx still exists in the codebase but is never imported or used anywhere
• This is dead code that should be removed

3. Unused UI Component File

• File: frontend/src/components/ui/button.jsx
• The button.jsx component exists in the UI directory but is not imported by any other component
• Should be verified whether it is used, and removed if confirmed dead code

4. Missing Public Assets Referenced in HTML

• Files: frontend/index.html, frontend/vite.config.js
• favicon.svg is referenced in index.html and the PWA manifest but may not exist in public/
• og-image.png is referenced in Open Graph meta tags but does not exist in public/
• logo.svg is referenced in the PWA manifest and as an apple-touch-icon

Proposed Fix

1. Set the footer year dynamically or correct it to the actual year
2. Delete frontend/src/context/DemoContext.jsx
3. Audit button.jsx usage and remove if unused
4. Verify existence of all referenced public assets and either create them or remove the references
