Add plain-permalinks (rest_route) golden URL table for every endpoint

Drive each of the 45 self-hosted endpoint URL builders through a
rest_route-seeded WpOrgSiteApiUrlResolver and assert the exact
?rest_route= URL, the plain-permalinks counterpart to the per-endpoint
wp-json golden assertions. Covers all three self-hosted namespaces plus
embedded-slash paths (plugins, block-renderer) and the api root.

This validates URL construction across the full endpoint surface on
plain-permalink sites; it complements test_login_plain_permalinks_mut,
which proves one endpoint end-to-end against a live server.

 - **Internal:** Documented how to pick an xcframework build for local work, and added `make help` descriptions for the `xcframework-only-*` targets. Verifying a UniFFI change needs only `make xcframework-only-macos`, not the full 11-target `make xcframework`.
 - **Internal:** Fixed `make xcframework-only-<platform>` building the per-target libraries but never assembling them into the xcframework. The `@# Help:` comments added for those `make help` descriptions became each rule's recipe and silently shadowed the shared `xcframework-only-%` pattern rule that ran the assemble step; each rule now runs the assemble step directly.
 - **Internal:** Update translations.
+- **Internal:** Added a golden URL table (`plain_permalinks_url_tests`) asserting all 45 self-hosted endpoints resolve to the correct `?rest_route=` URL on a plain-permalinks site, by driving each endpoint's real URL builder through a `rest_route`-seeded `WpOrgSiteApiUrlResolver`. Complements the per-endpoint `wp-json` golden assertions and the `test_login_plain_permalinks_mut` end-to-end test.
