fix: system-hub components - Add getTheme() and update ACL

Fixed two issues preventing components page from loading:

1. Added getTheme() method to theme.js
   - components.js was calling Theme.getTheme() which didn't exist
   - Added method to return theme data from SecuBox

2. Updated ACL to grant access to new methods
   - Added get_components and get_components_by_category to read permissions
   - Added luci.secubox methods (modules, modules_by_category, get_theme)
   - Resolves "Access denied" error (-32002)

This fixes the "Theme.getTheme is not a function" and "Access denied" errors.
