Remove spaces from all directory and file names

[horner]

Several directories and files in this repository contain spaces in their names, making URLs cumbersome and error-prone. For example:

• container creation
• nginx reverse proxy

URLs like these become difficult to reference and use:

• https://github.com/mieweb/opensource-server/tree/5f56b8d45b3c7e3dfddbbd1d247c5cdd7b3aecda/container%20creation
• https://github.com/mieweb/opensource-server/tree/main/nginx%20reverse%20proxy

Task:

• Audit the repository for all directories and files with spaces in their names.
• Rename them to use dashes (-) or underscores (_) instead of spaces.
• Update any references in documentation, scripts, or code to use the new names.
• Ensure that no links or imports are broken as a result of these changes.

This will help improve maintainability and usability of the repository.
