Subject: [PATCH] fix: properly configure Apache MPM Prefork with dedicated
 config file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Create dedicated apache/mpm_prefork.conf to override default MPM settings
- Mount mpm_prefork.conf to /etc/apache2/mods-available/ to properly apply limits
- Remove MPM config from nextcloud.conf (was being ignored)
- Set ServerLimit and MaxRequestWorkers to 400 (up from 150 default)
- Configure optimized worker settings for better concurrency

This fixes the "server reached MaxRequestWorkers" error that was causing
sync failures and 404 errors by properly overriding Apache's default
configuration file instead of trying to set it in conf-enabled.
