Add Public Project Listings Browser

[johneliud]

Description

Adds the public-facing marketplace pages where anyone can browse open project listings and freelancers can apply with their Stellar wallet. Also adds the "Projects" nav link to the Navbar.

Type of Change

• New feature

Changes Made

• app/projects/page.tsx — public listings browser: grid of listing cards (title, description excerpt, skill tags, XLM budget, milestone count, time ago); loading/error/empty states; no wallet required to view
• app/projects/[id]/page.tsx — Server Component resolving dynamic params
• app/projects/[id]/ListingDetail.tsx — Client Component with full listing detail (description, skills, milestones table, budget sidebar) and apply flow:
  • Wallet not connected → connect prompt
  • Connected as client (listing owner) → "Review applications" link
  • Connected as freelancer + listing open + not yet applied → message textarea + Apply button
  • Already applied → "Application submitted" notice
  • Listing filled → "This project has been filled"
• components/Navbar.tsx — added "Projects" link between "How it works" and "Freelancer"

Related Issue

Closes #38

Testing

• Tested locally
• All existing pages still load correctly
• npm run build passes with 0 TypeScript errors — /projects (static) and /projects/[id] (dynamic) both registered

Checklist

• Code follows the existing style
• No hardcoded secrets or credentials
• .env.example updated if new env vars were added
• README updated if setup steps changed
