Convert to Next.js with security features

- Migrate from Vite to Next.js 15 for server-side API support
- Add dynamic API route at /api/filaments that fetches from Confluence
- Implement security measures:
  - API credentials only accessible server-side
  - Security scan script to detect credential leaks
  - Tests to ensure no sensitive data exposure
  - Build-time security checks in CI/CD
- Update AWS Amplify configuration for Next.js deployment
- Update Terraform to use WEB_COMPUTE platform for Next.js
- Add Jest tests for API security
- Remove static JSON approach in favor of dynamic API

This provides real-time data updates while keeping credentials secure on the server.
