fix: global exception handler (prevents 502), transaction rollback on account create, CORS for reverse proxy

Browse Source 
- set_exception_handler in api/index.php prevents uncaught exceptions from crashing PHP-FPM
- AccountManager::create() wrapped in DB transaction with rollback + Linux user cleanup on failure
- CORS origin regex updated to allow requests from port 443 (NPM reverse proxy)
- index.html written via sudo tee instead of file_put_contents (www-data permission fix)
- chpasswd now called with sudo prefix
