fix: IIS sub-application deployment for production

Fixes 3 critical issues preventing production deployment on Windows IIS:

1. **IIS Sub-Application Path Stripping**
   - Changed URL patterns from ^roa2web/api/(.*) to ^api/(.*)
   - IIS sub-app at /roa2web automatically strips prefix
   - Requests arrive as /api/* not /roa2web/api/*

2. **SPA Fallback Absolute Path**
   - Changed from url="/index.html" to url="index.html"
   - Absolute paths (/) refer to site root, not sub-app
   - Relative path correctly serves from sub-app

3. **MIME Type Duplicates (500 Error)**
   - Added <remove> before <mimeMap> for .js, .json, .webmanifest
   - Prevents "duplicate collection entry" errors
   - Allows override of server-level MIME types

Build Script Improvements:
- Build-ROA2WEB.ps1: Copy public/ folder to temp build dir
- Build-ROA2WEB.ps1: Added verification logging for web.config
- ROA2WEB-Console.ps1: Fixed web.config verification location

Cleanup:
- Removed outdated web.config.10.0.20.36-INTERNAL
- Removed temporary test files and docs

Tested: https://roa2web.romfast.ro/roa2web/ - login page loads successfully
