Remove spaces from all directory and file names

[Copilot]

This PR addresses the issue of spaces in directory names that made URLs cumbersome and error-prone. Previously, accessing directories required URL encoding, creating unwieldy links like:

• https://github.com/mieweb/opensource-server/tree/main/container%20creation
• https://github.com/mieweb/opensource-server/tree/main/nginx%20reverse%20proxy

Changes made:

• Renamed ci-cd automation/ → ci-cd-automation/
• Renamed container creation/ → container-creation/
• Renamed dnsmasq service/ → dnsmasq-service/
• Renamed nginx reverse proxy/ → nginx-reverse-proxy/

Updated references:

• Updated all directory references in the README.md mermaid diagram
• Fixed directory links in the README.md documentation sections
• Updated .gitmodules to reflect the new path for the Proxmox-Launchpad submodule
• Re-initialized the submodule in the correct location

Result:

All URLs now use clean, dash-separated names that are easier to reference and share:

• https://github.com/mieweb/opensource-server/tree/main/container-creation
• https://github.com/mieweb/opensource-server/tree/main/nginx-reverse-proxy
• https://github.com/mieweb/opensource-server/tree/main/ci-cd-automation
• https://github.com/mieweb/opensource-server/tree/main/dnsmasq-service

No functionality is affected - only the directory names have changed to improve maintainability and usability.

Fixes #17.

@maxklema before I merge, I wonder if this is scary to you. I did not see that many cross references.

Looks good @horner. Not many cross-references because this repository is a combination of folders that are spread across our hypervisor and some core-infra containers. That's to say it's not an exact 1:1 replica, and folders on the actual machines use dashes (-) instead of spaces, unlike in this repository.
