fix(server): RSS SITE_ORIGIN + sitemap /page path

[Asakushen]

Summary

Two small SEO correctness fixes in server/src/index.ts. Verified still present on one-ea/Monolith@main before opening this PR.

1. RSS should prefer SITE_ORIGIN

Bug: /rss.xml builds channel/item links with new URL(c.req.url).origin only.

In the recommended Cloudflare setup, Pages Functions reverse-proxy /rss.xml to the Worker (client/functions/rss.xml.ts). The Worker then sees a *.workers.dev request origin, so the feed emits workers.dev absolute links instead of the public site domain.

Why this is real upstream: sitemap.xml and robots.txt already use c.env.SITE_ORIGIN || requestOrigin. RSS was left on request origin only. The env comment even documents SITE_ORIGIN for sitemap/robots, but not RSS.

Fix: use the same origin resolution as sitemap/robots:

const siteUrl = c.env.SITE_ORIGIN || new URL(c.req.url).origin;

2. Sitemap independent pages path is wrong

Bug: sitemap writes independent pages as /pages/:slug.

Frontend route is singular /page/:slug:

• client/src/app.tsx → <Route path="/page/:slug" ...>
• navbar / footer / admin page preview all link to /page/${slug}

So sitemap currently advertises URLs that do not match the app router.

Fix: emit /page/:slug.

Test plan

• With SITE_ORIGIN=https://example.com, GET /rss.xml channel/item <link> and <guid> use https://example.com, not the Worker host
• Without SITE_ORIGIN, RSS still falls back to request origin (previous behavior)
• GET /sitemap.xml independent page entries use /page/<slug> (not /pages/<slug>)
• Existing post/archive/home sitemap entries unchanged
• robots.txt behavior unchanged

Notes

• Single-file change; no client/branding/local customizations included
• Safe fallback retained when SITE_ORIGIN is unset
