Fix 404 errors for static assets with bot name prefixes

Removed root-level static routes (/:dir/*path) that conflicted with
bot name prefixes like /edu. Now all assets are served under /suite/
path, allowing the fallback handler to properly detect and strip
bot prefixes before resolving file paths.

Fixes:
- /edu/suite/js/api-client.js now returns 200 OK
- /edu/suite/css/apps-extended.css now returns 200 OK
- /edu/suite/admin/admin.js now returns 200 OK
- Base href injection working correctly for bot prefixes
