Versions

• Core version is v6.0.4 (Latest: v6.0.4)
• Web version is v6.0.1 (Latest: v6.0.1)
• FTL version is v6.0.2 (Latest: v6.0.2)

Platform

• OS and version: Debian 12.9

• Platform: VM in Proxmox 8.3

Expected behavior

When saving settings changes, all changes should take effect immediately upon save.

Actual behavior / bug

It appears that at least some settings require a manual restart of pihole-FTL.service.

Steps to reproduce

Steps to reproduce the behavior:

1. Go to Settings > All settings
2. Change the webserver.threads setting under the "Webserver and API" tab
3. Click the "Save & Apply" button; Pi-hole tells you it is applying your changes
4. The change to the number of threads has not actually been applied and will only be applied by manually restarting pihole-FTL.service

Screenshots

This is misleading because Pi-hole hasn't actually applied all settings, at least not all web server settings.

Additional context

I'm not sure what gets applied immediately and what doesn't; webserver.threads is just one example that I found does not get automatically applied. I discovered this during troubleshooting #2284 (comment).

Thank you. My research showed it is really limited to webserver.threads and #2295 will fix this.
