Changes:
1. admin-session.js: Use name attribute selectors instead of placeholder
- Changed: querySelector('input[placeholder="사용자명"]')
- To: querySelector('input[name="username"]')
- Reason: Placeholder selectors are fragile with DOM mutations
2. playwright.config.ts: Extend test timeouts for WASM boot
- Test timeout: 120s → 180s
- Expect timeout: 60s → 90s
- Reason: Blazor WASM bundle takes 60-120s to boot in local dev
3. tests/e2e/admin-login.spec.ts: Increase assertion timeouts
- Dashboard heading visibility: 20s → 60s
- Logout link visibility: timeout added 30s
4. tests/e2e/blog-crud.spec.ts: New comprehensive blog CRUD test
- Tests complete login flow
- Validates localStorage token storage
- Checks blog list page navigation
Status: Login form submission now works with proper field selection.
Remaining: Blazor WASM boot optimization needed for production.
