Summary

Adds a custom vector brand identity for the Decentralized Freelance Payment Platform, including an SVG logo, favicon, accessible React navigation component, and updated documentation header.

What it adds & why

• SVG Logo (rontend/public/logo.svg): Designed a clean, modern vector logo symbolizing decentralized trust on Stellar. It features dual interlocking orbital arcs (representing client and freelancer escrow counterparties), gradient nodes, and a central 4-point Stellar diamond star.
• Favicon (rontend/public/favicon.svg): Compact, high-contrast 32x32 vector favicon linked directly in rontend/index.html for crisp browser tab rendering.
• Brand Component (rontend/src/components/Logo.tsx): Reusable React component with accessible SVG markup (�ria-label,
  ole="img"), customizable dimensions, and toggleable brand text.
• Navigation Integration (rontend/src/App.tsx, rontend/src/styles.css): Integrated the brand mark into the main navigation bar linking back to / with smooth hover micro-interactions.
• Documentation (README.md): Added centered visual logo header to the project README.
• Test Suite (rontend/src/components/Logo.test.tsx): Unit tests covering SVG rendering, text toggling, and accessibility attributes.
