Subject: [PATCH] fix: restore Sitemap as Razor Page for search engine
 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem:
- SitemapEndpoint (FastEndpoints) creates /api/sitemap.xml
- robots.txt references /taxbaik/sitemap.xml
- Path mismatch breaks search engine crawling

Solution:
- Restore Sitemap.cshtml (Razor Page)
- Restore Sitemap.cshtml.cs (PageModel with BlogService)
- Remove SitemapEndpoint (FastEndpoints)
- Proper XML Content-Type handling
- Exact path match: /taxbaik/sitemap.xml

Why Razor Page?
- Razor Pages handle exact @page routes better
- Search engines know standard sitemap.xml paths
- No /api prefix routing conflicts
- Direct SSR rendering without endpoint routing

Verification for Google/Naver:
✓ /taxbaik/sitemap.xml (exact match with robots.txt)
✓ Content-Type: application/xml
✓ Valid XML structure
✓ Dynamic blog posts included
