Stable server fn endpoints: open tabs survive deploys

The 'previous question's resources until refresh' mystery: leptos's
auto-generated server fn routes embed a hash that changes across
builds. Every deploy therefore breaks every already-open tab - its
wasm keeps calling /api/get_question<oldhash>, the new server answers
400 'Could not find a server function at the route', and client-side
navigation quietly leaves the previous question's data on screen.
Refresh loads the new wasm with matching hashes, which is why it
always fixed it. Confirmed live: a pre-deploy client 400ed on
get_question2970801986613442004 while the freshly served wasm calls
get_question13103328088426240960, same source on both builds.

Explicit endpoint names decouple the URL from the build. This deploy
is the last breaking one; after it, old clients keep working.
