feat: collapsible admin menu, cache cleaner status module, update server URL

- Admin menu module now collapses by default, auto-expands on MokoWaaS pages (CB-style)
- Add mod_mokowaas_cache: one-click cache cleaner button in admin status bar (replaces Regular Labs Cache Cleaner)
- clearCache now purges all cache files (not just expired), matching RL behavior
- Update server URL changed to https://git.mokoconsulting.tech/MokoConsulting/MokoWaaS/updates.xml
- Add setupCacheModule() to package install script
