fix: dual-mount blogroll at /blogrollapi and /rssapi

/blogroll static page hardcodes /blogrollapi/api/* calls.
/news static page hardcodes /rssapi/api/* calls.
Both must work simultaneously.

- Revert mountPath to /blogrollapi (restores /blogroll page)
- Patch init() to also register publicRouter at /rssapi via a
  thin Indiekit.addEndpoint() alias (fixes /news page)
- /api/feeds alias retained for /news page (maps to listBlogs)

 /**
- * Patch: add /api/feeds alias for /api/blogs in the blogroll endpoint.
+ * Patch: dual-mount blogroll public API at /blogrollapi AND /rssapi,
+ * and add a /api/feeds alias for /api/blogs.
  *
- * The /news/ static page fetches /rssapi/api/feeds to populate the feed-source
- * filter dropdown. The blogroll endpoint exposes the same data under /api/blogs.
- * This patch inserts a /api/feeds route that delegates to the same controller.
+ * Problem: two static pages call different base paths:
+ *   /blogroll → fetches /blogrollapi/api/blogs, /api/categories, /api/items, /api/status
+ *   /news     → fetches /rssapi/api/items, /rssapi/api/feeds, /rssapi/api/status
+ *
+ * Solution:
+ *   1. Keep mountPath "/blogrollapi" (serves the /blogroll page as-is).
+ *   2. In init(), register a thin second endpoint at "/rssapi" pointing to the
+ *      same publicRouter so the /news page's fetches also resolve.
+ *   3. Add /api/feeds as an alias of /api/blogs on both routers.
