Spaces and other special characters in current directory path prevent Qlever setup-config and ui from running

[GravityCore]

If current directory's path contains spaces or any non-ASCII characters, then qlever setup-config and qlever ui fail.

Example error:

/bin/sh: 1: Syntax error: "(" unexpected
Could not copy "Qleverfile" to current directory: Command 'cat /mnt/c/Users/user/Problematic Spot/.venv/lib/python3.12/site-packages/qlever/Qleverfiles/Qleverfile.olympics | sed -E 's/(^ACCESS_TOKEN.*)/\1_LTOJSodzA4PM/'> Qleverfile' returned non-zero exit status 2.

Fix is simple: use quotes around all user-inputted paths (or all paths in general). So from

qlever-control/src/qlever/commands/setup_config.py

Line 53 in 017b08c

f"cat {qleverfile_path}"

change to:

f'cat "{qleverfile_path}"'

and

qlever-control/src/qlever/commands/ui.py

Line 132 in 017b08c

f"--volume $(pwd):/app/db "

change to:

f'--volume "$(pwd):/app/db" '

Other run commands that might be affected:

https://github.com/search?q=repo%3Aqlever-dev%2Fqlever-control+path%3Acommands+%22cd+%22&type=code

Might be a problem in other commands as well.
