fix: resolve Astro build errors in astro.config.mjs

- Remove assetsInclude yml which caused Vite to treat YAML files as static assets instead of running them through the custom YAML transform plugin; data.groups was undefined at runtime because the import resolved to a URL rather than parsed content
- Deduplicate old-path redirects: emit only the slash-less variant per service to avoid Astro router collision warnings (trailing-slash variant is handled automatically)
