1. Move flag reset outside conditional blocks - flags now always reset
even if ModSecurity is not installed or AJAX fails
2. Reset flags in error handler (cantLoadInitialDatas) as well
3. Add showLoader parameter to getOWASPAndComodoStatus - loader only
shows when explicitly requested, not during initial status check
This fixes:
- Toggle not responding to clicks (flags were stuck as true)
- Spinner showing on initial page load (now only shows during install)
