Add Post a Listing Page at /client/listings/new

[johneliud]

Description

Adds the page where clients can post project listings to the marketplace. Freelancers can then browse and apply via /projects. This complements the existing direct project creation flow at /client/projects/new (which is preserved for clients who already know their freelancer's address).

Type of Change

• New feature

Changes Made

• app/client/listings/new/page.tsx — Post a Listing form with:
  • Wallet connection gate
  • Title and description fields
  • Skills tag input — type and press Enter or comma to add, Backspace to remove the last tag
  • Dynamic milestone builder (same add/remove pattern as /client/projects/new) with title + XLM amount per milestone
  • Live total project value display
  • Validation: wallet connected, title, description, all milestone titles non-empty, all amounts > 0
  • On success → createListing() → redirect to /client
  • Cancel → back to /client

Related Issue

Closes #39

Testing

• Tested locally
• All existing pages still load correctly
• npm run build passes with 0 TypeScript errors — /client/listings/new registered as a static route

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
