Several templates had their own <script> blocks instead of going
through webpack like game1.js already does. Extracted the waiting
page, lobby page, and admin session-log tab scripts into their own
files under assets/, imported from the main app.js entry. Since
app.js is already loaded on every page, each module just reads its
own data-* attributes and no-ops if its target element isn't present
on the current page - same pattern game1.js already uses.
