Bug Description

ff53187 introduced sitemap.xml and robots.txt generation and was release in v0.18.1. This feature is now (as of v0.26.2) gone. Visiting /sitemap.xml and /robots.txt of an instance simply returns 404 (can be verified on official demo site).

This is a crucial features for public sites to work normally. Apart from SEO, many website collections require valid robots.txt and sitemap.xml as part of verification.

I tried to track release notes and code changes to find out when it's removed, but no release mentioned this removal and server/frontend/frontend.go seemed to be refactored and reorganized. Documentation linked v0.18.1 release note is invalid, and now "Admin" section doesn't mention this feature.

I wonder if this is an intended behavior or a bug during refactor? Thank you for your attention.

Steps to Reproduce

1. Set up an instance (or use official demo) with MEMOS_INSTANCE_URL configured correctly
2. Visit /robots.txt and /sitemap.xml

Expected Behavior

These URLs exists and contain valid data.
