All hardcoded paths (/load, /docs, /, /api/route/ etc.) are replaced
with url_for() in templates, so Flask's APPLICATION_ROOT and
ProxyFix generate correct URLs regardless of mount path.
For app.js (a static file), inject a URLS object from the template
alongside RELATION_ID:
URLS.routeApi, .segmentApi, .routeMasterApi, .routePage
Each is generated with url_for(..., relation_id=0)[:-1] to give a
prefix that JS appends relation IDs to. The popstate handler now
strips the URLS.routePage prefix instead of matching a hardcoded
leading slash.
